We have a NFS server (Linux) who stores files in a iSCSI disk array. This server is in production. The server and the array are very old and have to be replaced soon (the array is already in serious problems).
I have the replacement server and array ready in a different network.
I've been thinking about rsyncing the shares and then doing it again so I synchronize the data. I don't know if that could cause data inconsistencies... Since the shares are mounted over an lvm, maybe I could make a snapshot first?
QUESTION:
What is the best approach to migrate all the data? Do you have any advice?
