Restore when has two TSM servers

[ltcctl]

I'm just a newbie here. I just have seen some works and I wondering why it is.
In my new company, They have two TSM servers (1) and (2). One week ago, they have reconfigured a node to migrate it from (1) to (2). (all config now point to server (2))
Today, they need to restore data 1 year ago which stored on (1). They perform restore and TSM server automatically get data from server (1) while all the config files and TSM services still point to server (2). How can it be?
Can anyone help me to explain this case clearly?
Thank you very muchhhh ~~

You can have multiple config files in various locations

For ex: if "C:\TSM\dsm.opt" contains Server 1 configuration settings, you can connect to TSM BA client by pointing "C:\TSM\dsm.opt" opt file.

From CMD line
cd "Program Files\Tivoli\TSM\baclient"
C:\Program Files\Tivoli\TSM\baclient>dsmc -optfile="C:\TSM\dsm.opt" => this is to open BA client command line prompt
C:\Program Files\Tivoli\TSM\baclient>dsm -optfile="C:\TSM\dsm.opt" => this is to open BA Client GUI.

your client will connect to TSM server as mentioned in "C:\TSM\dsm.opt", from there you can perform backup/restore.
