My backup strategy involves using 'zfs send | zfs receive' to backup to an external 
USB drive. Will there be any problems backing up the upgraded pool to the 'not 
upgraded' external drive?

Assuming that backing up to a 'not upgraded' pool is doable then am I correct in 
assuming that in the worst case I could revert to 13.2 by doing a fresh install of 13.2 
and then restoring from a 13.2 snapshot on the backup drive.
