FAQ
Common questions about Microsoft 365 migrations.
What does a Microsoft 365 migration consultant do?
A Microsoft 365 migration consultant moves users, mailboxes, files, sites, and voice from a legacy environment into Microsoft 365 — and where there's an existing M365 tenant, modernizes it. Scope across a typical engagement: tenant-to-tenant migrations for M&A and divestitures, on-premises Exchange to Exchange Online, file shares to SharePoint and OneDrive, voice to Teams Phone, on-prem Exchange decommission, and tenant modernization (Conditional Access, Intune baselines, Defender XDR, Purview governance). Senior-led delivery, fixed-fee scope, vendor-neutral tooling. Most mid-market moves of 200-1,000 users run 6-12 weeks end to end.
How long does a Microsoft 365 migration take?
Mid-market moves of 200–1,000 users typically run 6–12 weeks: 1–3 weeks discovery, 1–2 weeks pilot, 2–6 weeks cutover, 2 weeks hypercare. Tenant-to-tenant moves and Exchange hybrid decommissions sit at the longer end of that band; net-new SharePoint or Teams Phone rollouts can finish faster. Larger or more complex tenants extend the cutover phase, not the methodology.
What does a Microsoft 365 migration cost?
Fixed-fee scope, defined in writing before kickoff. Pricing tracks user count, workload mix (mailboxes only vs. mailboxes + SharePoint + Teams), tenant complexity (single-domain vs. multi-domain, hybrid vs. cloud-only), and whether legacy on-prem Exchange decommission is in scope. We come back inside two business days with scope and a fixed-fee range — no hourly creep, no surprise change orders.
Which migration tool do you use?
Tooling is picked per workload, not per vendor relationship. ShareGate, BitTitan MigrationWiz, Quest On Demand, CodeTwo, and native Microsoft 365 Migration Manager are all viable depending on the source, the destination, and what's actually being moved. We don't resell any of them, so the recommendation reflects fit — not margin.
Do you do tenant-to-tenant moves for M&A and divestitures?
Yes. M&A integration (folding an acquired tenant into the parent's), divestiture (carving a business unit out into its own tenant), and rebrand or domain consolidation are the three most common drivers. Mailboxes, OneDrive, SharePoint sites, Teams chats and channels, and Power Platform apps all migrate. The same custom domain follows the users to the destination tenant when the legal structure allows.
Can on-prem Exchange be decommissioned after a hybrid migration?
Yes — and it should be. Microsoft now supports Entra ID-only recipient management for hybrid customers, so the 'one server for management' workaround from 2018 is no longer required. Exchange Server 2016 and 2019 reached end of support October 14, 2025; ESU Period 2 ends October 14, 2026. After that, no security updates are available. Decommissioning the last on-prem Exchange server is the right end state.
