How much does a SharePoint migration cost?
Data volume, the number of customisations and workflows, the quality of permissions – and how much is cleaned up beforehand – decide the effort. After the inventory you receive a reliable estimate. Cleaning up lowers the cost noticeably; dragging outdated data along is the most expensive mistake.
How long does the move take?
A manageable environment migrates in weeks, grown farms with custom developments take longer – a serious figure follows the analysis. Thanks to waves, first areas work in the new environment early instead of waiting for the overall finish.
Support for SharePoint 2016/2019 has ended – how urgent is this?
Since 14 July 2026 there are no more security updates; every newly discovered vulnerability stays open. That is no reason to panic, but it is a reason for a project with a clear timeline. Until the move, the risk can be contained – such measures cannot replace the migration.
What happens to our workflows and custom developments?
They are assessed: much of it Microsoft 365 now covers out of the box, the rest is rebuilt with Power Automate, Power Apps or SPFx – usually leaner than the original. A one-to-one copy of old customisations into the cloud is almost always the worst option.
Do we have to move everything to the cloud?
No. Workloads that must stay local for compliance reasons can run on SharePoint Server Subscription Edition or in Azure – hybrid, with a clear justification per workload. We recommend the cloud where it measurably takes work off your hands, not on principle.
Will our users notice the move?
Yes – and that is a good thing: modern interfaces, better search, Teams integration. To keep the change smooth, communication, pilot users and training are part of the project; migrating in waves keeps disruption to daily business small.
