Are these CIFS servers already configured on VDM? If so the file systems must also be mounted on the VDM. I am not sure what is the current configuration and how are you planning to use VDM.  If you don't have any VDM now, you can not simply create a VDM to perform CIFS servers migration - rather you need to configure the CIFS servers and the file systems on the VDM first.  If you are planning to do so, you may create only one VDM and configure both CIFS servers on the same VDM along with the file system - then you may use Celerra replication to replicate the VDM and the file system.  Anyway, another option may be separate the file system to make a new file system and copy the data for one CIFS servers to the new File system first.  Also, to your query, once you have moved one cifs server and the source file system to the new Celerra, the source file system becomes read only - but if you completely destroy the File system replication - then you can use the source file system as a separate file system with Read Write access.  I suggest, you consult your local EMC NAS person before making any decision and plan  Thanks,Sandip
 Guys, I am planning to use VDM to migrate the CIFS server from one Celerra to another in the same domain. The problem though is that VDM migration requires Filesystem to be migrated with the CIFS server and we have some filesystems that are shared by multiple CIFS servers. If i migrate this filesystem along with one of the CIFS servers using VDM, other CIFS servers will lose access to this filesystem after cutover because it will become read-only at source after cut-over. How do i workaround this?. Is it possible to do the following: After the VDM cutover is complete, the destination filesystem becomes read/write and the source filesystem will still be there in the source celerra as read-only. Can i make it read/write, so that the CIFS servers that are not migrated from the source can still access the filesystem at source?.  Thanks all.
