I have done a number of 2003 to 2011 migrations with varying issues and resolutions.
This is the first SBS 2008 to SBS 2011 I have done. This SBS 2008 source server was originally migrated from a source SBS 2003.
I'm using the migraqtion guide specific to 2008>2011 and I've done all the updates, BPA fixes, etc. I'm at the Prep Tool stage. ( http://technet.microsoft.com/en-us/library/gg615494.aspx#BKMK_RunTheMigrationPreparationTool
When the prep tool gets to "Expand Schema" it puts a red X next to it, then skips the next steps (licensing estension, Exchange) on that same page and lights up the continue button. If you continue, it runs the checks for issues on the next page and says there are no problems. The tool makes it all thw ay to the last page where you check the box for making a migration file without popping up an error. No errors are logged in the event logs.
Is it skipping all this because these steps were already done by the original migration from 2003>2008? Or is there a problem in the server that needs fixing?
Is it safe to proceed to create the file and install the other server? Will we still have the 21 day limit, will it migrate at all?
