Manually create CIFS and NFS shares ( we would be switching from NIS to integrated AD for authentication ) and using emcopy appears to the way to go as far as I can see.
- You need to configure a NDMP password both on the src and dst NAS server (sa/da option)
- src path can be a file system or a snapshot – check with CIFS/NFS/ftp that its valid
- dst path has to be on a writeable file system – on a replication destination NAS server you cannot write directly into / since that would be that NAS server root which isn’t writeable
- dst path directory will be created if it doesn’t exist – unless it’s on the NAS server readonly root
- ndmpcopy doesn’t support a single file as the src – so you need to copy at least a directory
- ndmpcopy works file based so src/dst can be any directory in the file system
- user and tree quotas as well as shares need to be recreated seperately on the dst if needed
Example:
Copying from the read-only manual checkpoint called “ro” of file system fs3_multi on a read-only dst NAS server of a Unity system to a writeable file system fs1_multi on another Unity system into directory restored_fs3
There's another approach that's valid as well, and much faster and easier as many customers can attest to, which is DobiMiner from my company, DataDobi. We're the only DellEMC Select partner in the migration category.
We're API Integrated with VNX, VNXe, Unity, Isilon, NetApp 7M, and NetApp CDOT/OnTAP9. So we can not only move the data, but also move the shares and exports; change source shares and exports to read-only at cutover, etc. We MD5 hash every single file source-to-target, and scale to multiple migration proxies handling both NFS and SMB from a single UI. Anyway, reach out if you'd like to see a demo, or drop by our booth at DellEMC World in about 10 days.

CIFS / NFS / multi-protocol ?
RecoverPoint is for SAN data

ndmpcopy is just like doing a backup the VNX and sending it directly over Ethernet to the Unity to restore
it will even automatically create a temp. snapshot on the VNX
you can use the ndmpcopy binary available from support.emc.com and run it on a Linux system
command line options for ndmpcopy can be a bit awkward
I could post an example later if people are interested
IF you are using file-level dedupe or DHSM (CTA) on the VNX you need to test if its copying the files correctly

you could also use ndmpcopy which preserves both Unix and Windows attributes

Using ndmpcopy from VNX / Unity to VNX / Unity
A Linux ndmpcopy binary is available from support.emc.com
https://download.emc.com/downloads/DL32451_NDMPCopy.zip.zip
it includes a man page
A couple of tips:
- You need to configure a NDMP password both on the src and dst NAS server (sa/da option)
- src path can be a file system or a snapshot – check with CIFS/NFS/ftp that its valid
- dst path has to be on a writeable file system – on a replication destination NAS server you cannot write directly into / since that would be that NAS server root which isn’t writeable
- dst path directory will be created if it doesn’t exist – unless it’s on the NAS server readonly root
- ndmpcopy doesn’t support a single file as the src – so you need to copy at least a directory
- ndmpcopy works file based so src/dst can be any directory in the file system
- user and tree quotas as well as shares need to be recreated seperately on the dst if needed
Example:
Copying from the read-only manual checkpoint called “ro” of file system fs3_multi on a read-only dst NAS server of a Unity system to a writeable file system fs1_multi on another Unity system into directory restored_fs3
service@unknown spa:~> ./ndmpcopy 10.245.19.153:/ro/test_fs3 10.245.19.147:/fs1_multi/restored_fs3 -sa ndmp:NdmpNdmp1! -da ndmp:NdmpNdmp1! -sport 10000 -dport 10000 -level 0
