I have a simple repository (120TB) which is running out of space, so I'd like to move all the backups on it to a new, larger repository. The repository is used as a target for backup copy jobs and holds all of the GFS restore points.
My idea was to add both repositories to a SOBR and then evacuate the old one. This would take weeks over a gigabit link and would prevent new restore points from being written while the data is being moved. So I came up with a plan but I'm not sure about the last part of it:
1) Add the old repository to a new SOBR, Veeam automatically reconfigures the jobs to point to the SOBR
2) Add the new repository to the SOBR
3) Seal the old extent
4) Veeam creates Active Full restore points on the new extent
5) Wait a week or so until all the incremental restore points have been removed from the old extent by the retention policy
6) Put the old extent into maintenance mode
7) Evacuate the old extent
I'm not sure about points 6 and 7, since the page about sealing an extent only mentions waiting until all the restore points are aged out (10 years

So, would this work?
