Transfer tape records to new tapes - best practise?

[BostjanUNIJA]

Hi.

Scenario:
VBR server
2 tape servers
2 tape libraries

OLD tape library (LTO6)
NEW tape library (LT08)

Idea:
We want to copy content from LTO6 tapes to LTO8 tapes

How we planned to achieve this.
- First we would restore content from LT06 tapes into VBR backup repository.
Then we want to pust that content to LT08 in most optimal way?
option a) New tape job (Backups to tape) and select to backup repository (to which LT06 content was imported)?
option b) Or a new tape job (Files to tape job) and select the imported backups and store them to LT08 tape?

Any other recommended way, to move content from LT06 tape to LT08?

Thank you.
