I've tested this now thoroughly and it works - can't believe this took 3 times to get right... huh.
Downtime planned starting Sunday 16 March; service will be down until migration to new Strato server is complete (worst case expect 3 days outage)!
Please ensure you have reasonable backups/copies of all important data!
