There's a need to migrate multiple source domains to the one target. Can ODM ADexpress do that?
It's possible for ODM ADexpress to migrate multiple sources to the one physical target, but there's a caveat.
In ADexpress, it's not possible to add environments manually. This is only done through the workflow creation wizard. This method forces creation of multiple pairs of source to the target, where each target environment, while might be the same physical environment, will be created as a separate environment in the ODMAD backend database.
For a true one-to-many or many-to-one scenarios, it's recommended to acquire a full ODM AD/Dirsync subscription, where environments can be added manually, and workflows customized to add environments as necessary. For example, a full ODMAD workflow can accommodate multiple environments and process them all in one shot.
