Our team recently finished a significant enterprise MOSS farm migration from a single-server installation to a multi-server farm topology. Once the new farm was architected and constructed, the migration went as smoothly as it could have, with no major obstacles. However, as a day or two passed, a few of the end users began to notice a strange occurrence.
This particular client is a heavy user of the My Sites and My Links functionality. During the migration, we used the User Profile Replication Engine, which is just one component of the SharePoint Administration Toolkit. This allowed us to migrate user profiles, and more importantly, specific user profile properties. The primary reason for this was to avoid an SSP migration, which is where the actual “My Links” are stored.
