When running the Windows Small Business Server 2011 Standard Migration Preparation Tool, keeps coming with the following error.
To prepare the source server for migration, you must be a member of all of the following security groups: Enterprise Admins, Schema Admins, and Domain Admins. For additional information, see the article at http://go.microsoft.com/fwlink/?LinkId=190413
I double checked the admin account is a member of these groups and it was, the solution turned out to be because the account was configured to use one of these groups as its primary group, I changed this in AD to domain users and the wizard ran without any problems at all.
