After 4 attempts, I finally managed to migrate @homeassistant on a PI4 to the Synology.
The backup/restore works, the trick is to: Backup; Download backup;Disconnect the PI;Install VM in Syno;Change IP in HA to the PI one;Restore;Wait.

@PJFDF @homeassistant what was the trouble you had?
@DiogoConstantino random freezes cuz the VM was badly created, plus the IP was not migrating cuz the PI was on :)
