We have over 100 file servers and all of them sending the copy of their data using DFS to one clustered server - File01.
So, for our migration it is not feasible to migrate all 100 servers all at once. Also, I tested and the two servers that are members of the replication group in DFS have to be in the same forest in order to replicate. The replication stops if I move one server in a different forest.
Please let me know what would be the other options to migrate file servers that all replicate to one server. For example, could we set another server in the target and to copy data there? Could we setup a new target folder for migrated file server? Should we migrate clustered servers first or last? Should we use robo copy to ensure data in sync? etc I think it will take extremely long time to copy the data to the new server if we choose other server as a replication partner.
