Migrating from SBS 2003 to SBS 2011

I am preparing to migrate from SBS 2003 to SBS 2011.  I have read through the migration instructions for SBS 2003 to SBS 2008, and am using that to guide me through the process.  However, it does not go into what to expect.  For example, it mentions that there will be irreversible changes made during the migration wizard, but it does not say what will be changed.

So here are my questions:

What changes will be made by the migration wizard?
Will we be able to continue using the SBS 2003 server after the migration wizard is performed and while the new SBS 2011 server is being configured?
If there will be server downtime, how long should we expect the unavailability to be?
Does the migration wizard require a restart?

I have other questions, but those will suffice for now.

Thanks!

Active Directory will be upgraded and the roles transfered


Will we be able to continue using the SBS 2003 server after the migration wizard is performed and while the new SBS 2011 server is being configured?

Yes you have 21 days before it will start complaining and shutting down

If there will be server downtime, how long should we expect the unavailability to be?

There will be server downtime, we normally do the migration out of hours allow 2 hours downtime, you won't need that but always allow extra time.


Does the migration wizard require a restart?

Yes both source and destination will be restarted throughout the process

Before you start the migration make sure you have a backup of the system state, they don't go wrong very often but when they do you will need the back up to restore your 2003 server to the stae it was in before the migration so you can start again
