Why did you decide to do a block-level copy, rather than file-level? Too many
partitions/LVM volumes/etc?  Personally I'd always recommend a file-level copy,
using something like rsync, which means no duplicate UUIDs, you aren't spending
time copying sectors that aren't referenced, the SSD gets fewer write cycles
and it can be interrupted and resumed. Or pvmove in some cases.
