Hi,
It is not supported even for initial placement:
Interoperability with Storage vMotion and Storage DRS
Due to some specific and limited cases where recoverability can be compromised during storage movement, Site Recovery Manager 5.0 is not supported for use with Storage vMotion (SVmotion) and is not supported for use with the Storage Distributed Resource Scheduler (SDRS) including the use of datastore clusters.
You can hit unexpected behaviour / issues.
Michael.
