Yep, I would be very surprised if what you're planning to do would
result in problems, as I've done several such operations in the past
without any issues. I've never had much to do with LVM, but the last
time I was doing this sort of thing I dd'd source drive to target
drive, resized /home (the last partition I always create) to fill the
new, larger disk, and that was that, the machine instantly booted fine.
Not exactly the same thing you are doing (especially as LVM is
involved in your setup), but I can see no major difference between
these two cases that looks like trouble.
Greetings,
Nils
