Project Server end of support: three paths

Project Online carries a retirement date of September 30, 2026 — 42 days from this update — and it is not listed on Microsoft's roundup of products ending support in 2026. Project Server 2016 and Project Server 2019 both reached end of extended support on July 14, 2026; that date has passed and there is no ESU program for Project Server. Project 2021 and Project 2021 (LTSC) on the desktop both end on October 13, 2026.

Update — August 19, 2026: Project Online retires in 42 days, and Microsoft's own 2026 roundup page does not list it. Two things are worth pinning down precisely, because both of them change what an administrator does this week.

1. The date is literally September 30, 2026. Microsoft's Project Online lifecycle listing renders its Support Dates row as Project Online | 3/1/2013 8:00:00 AM | 9/30/2026 8:00:00 AM, under a column headed Retirement Date. The 8:00:00 AM is the part to notice: it is not the 6:59:59 AM end-of-previous-day encoding Microsoft uses elsewhere in these tables, so there is no minus-one-day adjustment to make here. September 30 is the date. The same page records that Project Online follows the Modern Lifecycle Policy, and Microsoft's verb is retirement rather than "end of support" — under Modern Policy the service goes away, rather than merely stopping updates. From the date of this update, that is 42 days.

2. It is absent from the page an administrator would check. Microsoft's products ending support in 2026 roundup, as published on August 19, 2026, does not contain the string "Project Online" in any of its five tables. What it does carry is four other products with "Project" in the name: Project Server 2016 and Project Server 2019 under "Products reaching End of Support" at July 14, 2026; Project 2021 under "Product Retirements" at October 13, 2026; and Project 2021 (LTSC) under "End of Support" at October 13, 2026. Four entries, across three tables, on two dates — and the one Project product that goes away in six weeks is on none of them.

There is no point to score here. The practical consequence is simply the argument this post already made: an administrator who checks the obvious summary page gets a correct answer about the servers and the desktop, and no answer at all about the service most of them are planning to migrate to. Check the destination on its own lifecycle page, not on a roundup. It is two clicks, and you can verify both of the statements above yourself.

If you are running Project Server 2016 or 2019, the runway is already gone. Both versions reached end of extended support on July 14, 2026. Microsoft's lifecycle tables record an Extended End Date of 7/15/2026 6:59:59 AM Pacific for each — that is the timestamp boundary, so July 14 is the last full day. There is no Extended Security Updates program for Project Server at any price.

That much is a normal end-of-support story, and if it were the whole story the answer would be the usual one: pick the cloud destination and go. It is not the whole story, and the reason is the part most teams discover in week three.

The destination most teams name first retires before you finish

Ask a team what replaces on-premises Project Server and the first answer is almost always Project Online. It is the obvious name. It is the Microsoft-branded cloud version of the thing they already run.

Microsoft's lifecycle listing gives Project Online a retirement date of September 30, 2026. Project Server 2016 and 2019 died on July 14, 2026. The destination has a shorter remaining life than the thing you are leaving — by roughly two and a half months.

This is not a subtle trap. It is a published date on a public lifecycle page, and it inverts the entire migration plan. A Project Server–to–Project Online project scoped in good faith in the spring would have landed its users on a platform that retires before the change management finished. Anyone still holding that plan should stop and re-scope, because the second migration costs more than the first — you pay for the move twice and spend the credibility once.

It is also easy to miss, and that is not the reader's fault. Microsoft's roundup of products ending support in 2026 lists Project Server 2016, Project Server 2019, Project 2021 and Project 2021 (LTSC) — and does not mention Project Online anywhere on it. If a summary page is where your organization checks dates, the one Project product without a listed successor is also the one you will not see. Treat a product's own lifecycle listing as the source and the roundup as a convenience.

On what we are not claiming. The lifecycle listing links out to Microsoft's own retirement guidance at aka.ms/pjoretirement, but that article's body renders client-side and we could not read it from a server-side fetch. So we are working from the lifecycle date, which is published and machine-readable, and we are deliberately not repeating second-hand claims about grandfathering, extensions, migration tooling, or what happens to tenant data afterward. If a vendor or a blog tells you the date has moved, ask them which primary source says so.

Path one: Planner

Microsoft's forward path for work and project management is Planner, into which it has consolidated Project for the web, the older Planner, and To Do. For most mid-market organizations coming off Project Server this is the right destination, for the ordinary reason: it is where the vendor's investment is going, and it is the only option on this list with no published end date attached to it.

The honest caveats. It is not a like-for-like replacement for a mature Project Web App — the scheduling engine, enterprise custom fields, resource-pool semantics and timesheet model are not the same, and a portfolio built around Project Server's reporting contract will not lift cleanly. Licensing is its own conversation: what Planner Plan 1 buys versus Planner and Project Plan 3 decides whether the destination can actually hold your use case. Establish that before the migration, not after, because it is the question that most often reopens a closed scope.

Path two: Project Server Subscription Edition, on-premises

Staying on-premises is a real path, and for organizations with genuine data-sovereignty or regulatory constraints it is sometimes the only one. Project Server Subscription Edition is supported and is the on-premises continuation.

But price it honestly, because it is not a Project decision. Project Server ships inside the SharePoint Server Enterprise installer. It is not a separate product with a separate install; its files arrive in the SharePoint Enterprise MSI, and it can only be enabled on the Enterprise edition — never Standard. Project Server Subscription Edition requires SharePoint Server Subscription Edition Enterprise underneath it.

So this path is a SharePoint Enterprise licensing and upgrade project wearing a Project-shaped label. And SharePoint Server 2016 and 2019 went out of support on the same day, July 14, 2026 — which means the farm underneath your Project Server is in exactly the same position. If the database tier is SQL Server 2016, that went out of support that day too. Three tiers, one date. Scope all three together or the third one arrives as a change order.

Path three: off the Microsoft PPM stack

The third path is leaving. If your organization's Project Server usage is really scheduling and portfolio reporting rather than deep Microsoft integration, the migration budget you are about to spend is also a reasonable moment to ask whether a third-party portfolio platform fits better. That is a genuine option and we will say so when it is the right answer — we take no resale margin on any destination in this post, including Microsoft's.

The test is integration depth. If Project data feeds Power BI models, Entra-governed permissions and SharePoint-hosted project sites that the business actually uses, leaving is expensive. If Project Web App is effectively a scheduling tool with a resource pool attached, it is not.

Don't forget the desktop, which has its own date

The server is not the only surface with a 2026 date on it. Project 2021 and Project 2021 (LTSC) both end on October 13, 2026 — and they get there by different mechanisms, which is worth understanding because it changes what "end" means.

  • Project 2021 follows the Modern Lifecycle Policy and carries a Retirement Date of 10/14/2026 6:59:59 AM Pacific.
  • Project 2021 (LTSC) follows the Fixed Lifecycle Policy and reaches its Mainstream End Date on the same timestamp — with no Extended phase listed at all.

For the LTSC build in particular, there is no extended-support tail to fall back on. Mainstream end is the end. Teams that bought LTSC precisely to avoid a subscription are the ones most likely to assume an extended phase exists here, and on this product it does not.

What to do this month

The first task is not a migration, it is an inventory — and it is smaller than it sounds.

  1. Establish which surface you are actually on. Project Server 2016, Project Server 2019, Project Online, Project Professional on the desktop, or Planner. Organizations frequently run two of these at once and have only budgeted for one.
  2. Write down which date binds each one. July 14 2026, September 30 2026 and October 13 2026 are three different clocks on three different surfaces, and they are not interchangeable.
  3. Check the tiers underneath. The SharePoint farm and the SQL instance. On this stack they usually share the July 14 date, and finding that out late is what turns a Project migration into three.
  4. Inventory the customization tail before estimating. Custom fields, lookup tables, enterprise calendars, timesheet configuration, and the permission mode the farm is in. This is the scheduling variable, not the project count.
  5. Then pick the destination — and check the destination's own lifecycle page before you commit to it. Its own page, not a summary or a roundup: the roundup is where Project Online is missing. That single step is what this whole post exists to make routine.

The 30-second version

Project Server 2016 and 2019 ended support on July 14, 2026 — that date has passed, and there is no ESU program. Do not migrate to Project Online: it retires September 30, 2026 — 42 days from this update — before the thing you are leaving finishes dying, and it is not listed on Microsoft's roundup of products ending support in 2026. Three real paths — Planner for most, Project Server Subscription Edition where sovereignty demands it (priced as the SharePoint Enterprise decision it actually is), or off the Microsoft PPM stack entirely. The desktop has its own date: October 13, 2026, and Project 2021 (LTSC) has no extended phase behind it. Inventory the surface, the date that binds it, and the tiers underneath — then pick a destination and check its lifecycle date first.

Questions we get asked

When did Project Server 2016 and 2019 reach end of support?
Both reached end of extended support on July 14, 2026. Microsoft's lifecycle tables show an Extended End Date of 7/15/2026 6:59:59 AM Pacific for each, which is the timestamp boundary — July 14 is the last full day of support. Project Server 2016 left mainstream support on July 14, 2021; Project Server 2019 left mainstream on January 10, 2024, so it spent only two and a half years on extended support. There is no Extended Security Updates program for Project Server at any price, unlike SQL Server 2016 which has a paid ESU ladder. An unmigrated Project Server farm is receiving no security updates today.
Is Project Online a safe destination for Project Server data?
No — and this is the single most expensive mistake available on this migration. Microsoft's lifecycle listing gives Project Online a Retirement Date of September 30, 2026, rendered as 9/30/2026 8:00:00 AM. That 8 AM timestamp matters: unlike the 6:59:59 AM boundaries used elsewhere in Microsoft's lifecycle tables, it means September 30 literally, with no minus-one-day adjustment to make. Project Online follows the Modern Lifecycle Policy, and Microsoft's word for what happens is retirement rather than end of support — the service goes away rather than merely stopping updates. That date is after the July 14, 2026 date you are leaving. Migrating from Project Server to Project Online means moving onto a platform with a shorter remaining life than the one you are abandoning, and paying for the migration twice. Check the destination's own lifecycle page before you scope the move.
Is Project Online listed on Microsoft's page of products ending support in 2026?
No. As published on August 19, 2026, Microsoft's 'Products ending support in 2026' roundup does not contain the string 'Project Online' in any of its five tables. It does list four other products with Project in the name: Project Server 2016 and Project Server 2019 under 'Products reaching End of Support' at July 14, 2026; Project 2021 under 'Product Retirements' at October 13, 2026; and Project 2021 (LTSC) under 'End of Support' at October 13, 2026. The Project Online retirement date is published — it is on Project Online's own lifecycle page, as a Retirement Date of September 30, 2026 under the Modern Lifecycle Policy. The practical lesson is that a roundup page is a convenience, not the source. Check the destination product's own lifecycle listing before you commit a migration to it.
Project Online, Project Server, Project 2021 — which one am I on, and which date binds it?
Four different products share the name, and they carry three different dates. Project Server 2016 and Project Server 2019 are the on-premises server products; both reached end of extended support on July 14, 2026, and there is no ESU program for either. Project Online is the Microsoft-hosted cloud service, and Microsoft's lifecycle listing gives it a Retirement Date of September 30, 2026 under the Modern Lifecycle Policy. Project 2021 and Project 2021 (LTSC) are the desktop clients, and both end on October 13, 2026. Organizations frequently run two of these at once — a server farm plus desktop clients, or a cloud tenant plus desktop clients — and have budgeted for one. Establish which surface each user is actually on before you pick a date to plan against.
What are the three paths off Project Server?
One: Planner, which is where Microsoft has consolidated Project for the web, Planner and To Do — the supported cloud destination. Two: Project Server Subscription Edition on-premises, which is a real path but is gated behind a SharePoint Server Subscription Edition Enterprise licensing and upgrade decision, because Project Server ships inside the SharePoint Enterprise installer rather than as a separate product. Three: off the Microsoft PPM stack entirely, onto a third-party portfolio platform. Project Online is not a fourth path; it retires first.
Why does the Project Server decision depend on a SharePoint decision?
Because Project Server is not a standalone installation. Its files ship inside the SharePoint Server Enterprise MSI and it can only be enabled on the Enterprise edition, never Standard. The same holds for Project Server Subscription Edition against SharePoint Server Subscription Edition Enterprise. So the on-premises Project path is a SharePoint Enterprise licensing and upgrade decision wearing a different name — and SharePoint Server 2016 and 2019 went out of support on exactly the same day, July 14, 2026. Scoping Project separately from the farm is how a Project migration becomes an unplanned SharePoint project in week three.
What happens to Project Professional on the desktop?
Project 2021 and Project 2021 (LTSC) both end on October 13, 2026, but by different mechanisms, and the difference matters. Project 2021 follows the Modern Lifecycle Policy and carries a Retirement Date of 10/14/2026 6:59:59 AM Pacific. Project 2021 (LTSC) follows the Fixed Lifecycle Policy and reaches its Mainstream End Date on the same timestamp — with no Extended phase listed at all. For the LTSC build there is no extended-support tail to fall back on; mainstream end is the end.
How long does a Project Server migration take?
The dominant scheduling variable is not the project count, it is the customization tail: custom fields, lookup tables, enterprise calendars, timesheet configuration, and whichever permission mode the farm was left in. A Project Web App with a light configuration and a few dozen active projects is a matter of weeks. One with a mature PMO practice, custom fields wired into reporting, and OLAP dependencies is a genuinely different engagement — and usually needs a Project specialist alongside a migration team. Inventory before you estimate.
