Move /nsr in another path

Actually we have NSR directory mounted in a LUN (/dev/mapper/vgnsr-lvnsrdb        985G  222G  713G  24% /nsr) on a storage need to be replaced.

We want add another LUN on a new storage. So I need to relocate this data to the new volume.

I think the main steps are as follows:
1. Make a NMC server backup. Or is needed to have a backup of the index and critical files in the /nsr directory with "savegrp -O" command? 
2. Stop the NetWorker services.
3. Copy of the data from the /nsr directory to the new path (/nsr_new), keeping the same permissions.

4. rename /nsr in /nsr.old and /nsr_new in /nsr.
5. Make a symbolic link from the new path to /nsr. 
6. Check if is necessary to update the paths in the client configuration.
7. Restart networker services

Do you see other steps to do? Do you think there could be any problems?

Thanks for your assistance
