I think there is some confusion on the replies. This isn't the migration wizards for SEP, it the migration wizard for Windows 7 (USMT for small migrations)
SEP Version 11.0.6005.562. I will be upgrading to 12.1.1 in the next few weeks.
I don't have any block of wireless settings configured.
The old computer and new computer are in the same SEP group so policies are identical.
Rerunnning the MSI from the distribution point fixes the problem.
