Just for once, I wanted to state that I am deeply impressed by the work
done with LVM. I have just just copied all my data from my old RAID to
my new RAID while continuing to work with the data using pvmove.
Compared with what I had to do several years ago, this was a great
experience. I know, of course, that professional operators do this "all
day", but doing it yourself for once felt great.

Just one question, though. I couldn't find anything about using pvmove
together with lvm cache. So to make sure, I removed the SSD caching
before pvmove and added the caching again afterwards. Would it have been
safe to leave the caching active during the pvmove?

No, fairly certain pvmove wouldn't have allowed the caching layer.  So
you did the correct sequence.
