I asked them if it's possible to move current VPS VMs to the UK region, the answer seems to be yes:
Thank you very much for your reply.
Moving your VPS to a different region is possible. Please find a full overview on the migration procedure in our documentation https://docs.contabo.com/docs/products/Cloud-VPS-and-VDS/migration/ .
You can start the migration process at any time using your customer control panel at https://my.contabo.com/abos# by clicking on "Manage" right next to your VPS and by choosing the option "Move to other Region" there.
How nice was my reply?
Awesome Nice Boo!
