I think if you ask 10 people you'll get 10 different answers.

The easiest to *explain* is:
* backup /home
* clean install the OS using Custom partitioning's "LVM" preset
partitioning scheme
* restore /home from backup

And that's because the installer does a lot of work you otherwise have
to do manually: creates and assembles the new setup, writes out the
correct bootloader and fstab information, etc.

If you know how to do these things manually already, then that path is
probably easier than a clean install, and having to reinstall some
things and adjust settings. Explaining all that in detail is tedious,
but maybe someone knows of a guide how to do all that.

But this process is the same whether the source is btrfs, xfs or
already ext4 and you need to migrate it to new file systems/layout.
