Hi all! Hope things are going well!
**Sorry, there is a wrong title of topic → we need to migrate from LTO8M to LTO8**
I am coming to you with a question.
We were using LTO8 tapes in our storage policies, then due to savings someone decided to start using LTO8M… now all recent backups are written on LTO8M

And we do have some older backup on LTO8 and some on LTO8M:

What we need to do is to have all those date on LTO8 due to some compatibility problems.
So my question is - is there a way to migrate those data from LTO8M to LTO8 within this one particular copy? We have calculated and to store all data we would need around 100 new tapes of LTO8, but about half data is already on LTO8 tapes.
We thought about creating a new synchronous policy, but it will require all data to be rewritten on new LTO8 tapes, we would like to avoid that because we already do have part of data on LTO8.
I would be glad if you have any tips which might avoid us buying unnecessary amount of new tapes.
