I have DEV and PROD SharePoint 2010 Server environments. DEV is a copy of production a few months old. The User Profile configuration is, I believe, identical. Same sources, same FIM. However, the number of user profiles in Production is greater than that in DEV, even though the Profile DB used to create DEV's was copied and attached from PROD a few months ago. Production has around 3000 users, DEV is around 70 users short at 2930.
I did a compare of the DEV/PROD users from respective PROFILE DBs and I'm not finding anything singular about those missing from DEV. They're from different domains. 35 of them are test accounts, which are interesting.
Any ideas? Thanks.
