There's no best approach, it depends.
So there are a lot of variables that can affect which method you pick:
- are you moving the tape library to the new location?
- do you have a long or short timeline to to this?
- is there a deadline to decommission/return the old hardware?
- is there special applications that cannot have a long TSM outage?
- are you using dedup and node replication?
Your options are:
- treat it as a DR and restore your entire TSM environment to the new environment. Longer outage, but you would finish quicker.
If you want to do it in stages, then setup the new environment, you have 2 options, both require to setup the new environment as a new server first and will take several weeks, but minimal outage:
1 - setup the new server and node replication, then start replicating each node to the new server, then permanently switch the nodes to the new server before shutting off the old
2 - move node one by one to the new server and start doing backup, after a certain period of time the new environment is up and you feel you no longer need the old environment, discard it
3 - set server to server communication and export each node one by one, after each one is exported, update the option file on these nodes to point to the new server
