We are doing a migration from Exchange 2003 (SBS 2003) to Exchange 2011 (SBS 2011) and everything has gone swimmingly other than migrating the public folders.
We went into the admin console and set the public folder to move to the Exchange 2011 box.
The public folder instance directory is still showing objects in there on the Exchange 2003 box, meaning the migration didn't occur.
We're at a loss at why since there are no errors. It's been about 10 days, so plenty of time for the migration (which we know can be slow). These aren't huge public folders.
