As we are running through our SBS v7 migration to SBS 2011 RTM, we are discovering all sorts of nuances with the migration process. This was the case when migrating from SBS 2003 R2 to SBS v7, and now is also the case with this migration.
Once the migration process has been started, the Migration Wizard has a countdown timer built right into it:
Given that we will be running a number of migrations to SBS 2011 over the next few months, having that little indicator can be very helpful.
When migrating to SBS 2008 we always set a timer in place for the particular migration we were working on but could never be 100% sure that the source server would start misbehaving when our timer hit 21 days.
Here we can be reasonably assured that when that statement says 1 day we better have our stuff together and be ready to demote and remove the source SBS from the domain!
