Import a zpool whose name is already taken

I would like to import a zpool from another system whose name is already used. The import via the gui from TrueNas aborts with an error message. In that case the zpool named Raupe.

zpool import -f Raupe Raupe_old

zpool list Now Raupe_old should be listed with

zfs set mountpoint=/mnt/Raupe_old Raupe_old

now both pools should be mounted in / mnt
