Is the source Distribution List (DL) automatically hidden when it is migrated in a site to site Intra-Org migration?
Exchange Migrator 1.1
Once the source DL has been migrated, the source DL will continue to be visible in the GAL. A recommendation is to manually hide the source DL's after you have migrated them to the target. The effect is to lessen any confusion that may be caused with the same DL listed multiple times.
The request for this type of functionality, to automatically hide the source DL after it as been migrated, is being considered for a future release. At this time, however, there has been no decision made to include this feature.
