Mixing different Linux hardened repositories in SOBR

[Sam31Tls]

Hello veeam gurus and practitionners!
i am quite confident it will work but better safe than sorry, please confirm it to me!
Is it possible to mix, within a SOBR, as performance tiers :
- 1 brand new Veeam hardened linux rocky linux repository extent
- 3 old extents from an Ubuntu hardened repo soon to be decommissioned.

The sceario to migrate data would then be to seal to old extent, evacuate the third, oncee done and in maintenance remove this extent from the SOBR.
Then evacuate one of the two sealed remaining old extent, etc.
Finally having only the new extent in te SOBR; whitch leaves a last question : in order to maximise the reflink\xfs space saving feature, can i keep it as a single extent in the SOBR or should i remove it as well of the SOBR?
NB : vmware-vsphere-f24/sobr-with-linux-hard ... 91273.html forum was interesting regarding reflink aspect but not really responding to this particular question.

Thanks a lot!

You should be on Per-Machine backup files, so no real savings from making one massive extent.

@haslund : thank you! So i can leave this single extend in the SOBR.
And what about mixing the rocky and ubuntu repositories in the SOBR, no worries to anticipate in your opinion?
