What size are the partitions on the old 8TB disks?
Is it a single partition for all 8TB ?
If you have a separate data from the OS partition:
you could "rsync -avpP"  the data/image/picture/whatever files over to
the new disks on top of LVM.
You could handle the OS partition offline.
You can then do a final "catch up" rsync of the data in offline mode.

Once everything is copied and you have unmounted the old disks, and
have everything booting and running nicely on the new disks.
You could then wipe the old disks, and redo them with LVM on them.

I would allow at least a day or two for the first rsync of 8TB.

Kind Regards
