I could not find a log so checking process could be a method.However, if the migration takes that long, if possible it would be good to reduce retention time for end system events and after the DB decreased enough try again ?You can rerun the migrate...
hint, ipforwarding should be enabled on each vlan, not just on internetten. And what about NAT ? Does the internet router knows these IP's ? Routing needs to be working both ways.
