This is a followup question to the following topic: https://discussion.fedoraproject.org/t/updating-from-32-to-33/66419.
As was mentioned, upgrading from Fedora 32 to 33 will work flawlessly, even if the filesystem is set to ext4.
However, since the coming Fedora releases will all be based on btrfs, will I encounter problems in the long term if I keep my disk formatted in ext4?
Please don’t get me wrong: I actually endorse the change to btrfs, and will choose it if getting a new machine. It is only that I fear upgrading my current system to btrfs, since I need it constantly due to my studies, and I don’t know if my (ext4) backups will be compatible if something goes wrong.
So, will the upcoming Fedora releases (34 etc) work if you still have ext4?
Thank you very much and keep the nice work up
