    Farm solution, SharePoint Framework or external service: deciding each customisation on Subscription Edition

    SharePoint 2016, 2019, Subscription Edition and Online: what actually changes

Whether a fleet is already on Windows 11, paying for Extended Security Updates, or simply exposed, the decision underneath is the same: swap the PCs, or use the forced move to modernise the workplace behind them.

    Every migration interrupts somebody. The work is deciding which interruption is acceptable, for whom and for how long, and measuring it in rehearsal before promising it. What that means when the destination is Subscription Edition and when it is SharePoint Online.
