I read a lot of information on the net that a clean install was the only way to migrate, but after installing it on my Laptop computer, I decided that the ext4 file system and the btrfs file system are structurally the same, so I migrated to the btrfs file system using the ext4 file system. After a clean install of Tumbleweed with btrfs (with the same kernel as the backed up system), I restored the backup and it is working fine. I often install and test new software, and usually restore the backup I took with rsync before the test after the test is finished, and this has never caused any problems. I hope this helps. Regards & A little early, but Good Night. --- ┏━━┓彡 野宮 賢 mail-to: nomiya @ lake.dti.ne.jp ┃＼／彡 ┗━━┛ "Maddox hopes that empowering users to pick their own algorithms will get them to think more about what’s involved in making them.
