Old faulty Tape Library replaced with a new one

Hi, hope you all are having a good time.

I just faced a tape library issue and after trying fixes ultimately the hardware vendor replaced it with a new same model library.

Now that the library has been replaced, we now have a new robot configured, however the old cartridges (holding valid data) are still under the old robot and volume group.

I need to move those cartridges under new robot. I wanted to know the steps to be followed after i have inserted those cartridges in the new library.

Environment information:

Netbackup version 7.5.0.4

OS (AIX 6.1 : Master) and (Windows 2008 R2 : Media Server).

Tape Library (Dell PowerVault TL4000 Tape Library : LTO5)
