Wir haben erfolgreich von cluster26 -> cluster27 migriert.
Zurück geht es aber nicht:

Beide haben im GUI einen Storage mit zfs_local

Wir sind für Tipps dankbar.

migration alt -> neu sollte immer funktionieren. migration neu -> alt ist best-effort und kann bei inkompatiblen aenderungen unter umstaenden nicht funktioneren. 6.3 ist sehr weit weg von 7.1, hier wird es einige dinge geben die nicht kompatibel sind..
