Hello everybody,
thank you all for the information.
Unfortunately i do not fully understand, how to manage the shrinking.
For now, i will install the new linux on a external disc, boot and then
copy content from the f38 installation.


Am I correct in thinking you were able to shrink the btrfs filesystem,
but are unable to find software to adjust the partition size to match?

You could use the new disk for a backup, then shrink the oversized partition.
See: https://feldspaten.org/2018/06/01/resizing-btrfs-max/ -- shrink the
btrfs filesystem a bit smaller than you want, use fstab to resize the partition,
then expand btrfs to use the full partition.

https://itsfoss.com/btrfs/ lists the advantages of btrfs

Yes you are right. I could shrink the filesystem.
My problem starts, because gparted complains a warning, that it is possible not able to boot.
therefore i cancel the operation and read a bit deeper.

 
the old way, long and work intensive (finding the correct partition
size, choose the filesystem typ and so on.).
i think, it is annoying, that btrfs with f38 is so hard to use for this
task.
my new filesystem will not be btfrs.


All filesystems need backups.  It seems wasteful to do an extra install.
