The number one fear about cloud migration is disruption. The reality, done properly, is that most of the work happens invisibly — and the actual “switch” is often a weekend or an evening.
Realistic timelines for typical projects
Email to Microsoft 365 (10–50 users): 2–4 weeks end to end. Mailbox moves happen in the background while people keep working; the only noticeable moment is updating Outlook profiles, usually done overnight or in a single morning.
Files to SharePoint/OneDrive: 2–6 weeks depending on volume and how much spring-cleaning you do first. Copying data is the easy part — deciding what to keep is the real project.
Server workloads to Azure: 4–12 weeks. Line-of-business applications need the most planning, because they need testing properly before anyone relies on them.
Full “server closet retirement”: typically one to two quarters, phased so nothing is ever rushed.
How downtime stays close to zero
- Nothing is deleted until the new system is proven. Old and new run side by side.
- Migrations happen outside working hours wherever possible.
- You migrate in phases, starting with low-risk workloads, so lessons learned apply to everything after.
- There’s always a rollback. If anything misbehaves, you revert and try again — nobody heroically presses on.
What causes delays (so you can avoid it)
- Undocumented applications nobody admits to using
- Ancient servers that “must” come too (often they mustn’t)
- No decision-maker available for sign-offs
- Leaving the spring-clean of old files to the last minute
A proper assessment up front surfaces all of these in week one. That’s exactly why our migrations start with a free consultation and technology assessment — so the plan you’re given is the plan that actually happens.
