Regarding NVME see the issue
which means you need at least Relax-and-Recover version 1.18
to have support for NVME SSD disks.

In general migrating a system onto different hardware
does not "just work".

In sufficiently simple cases it may "just work" but in general
do not expect too much built-in intelligence from a program
(written in plain bash which is not a programming language
  that is primarily meant for artificial intelligence ;-)
that would do the annoying legwork for you.

To migrate a system onto different hardware you usually
have to adapt your disklayout.conf from the "old" system
to make it appropriate for the "new" system.

For an example you may have a look at the
"P2V HP microserver to VmWare" issue

To mitigate the annoying migrating legwork a bit,
I recommend the newest rear GitHub master code that provides
some first steps for RECOVERY_UPDATE_URL support.

See default.conf how RECOVERY_UPDATE_URL is meant to work:

For an example how RECOVERY_UPDATE_URL works see

But when you use the latest rear master code see
what is special about the disklayout.conf file location
in the recovery system that you must consider
