In case you have to migrate server which is behind firewall perform below steps:
- MS KB article how to limit port range for RPC – KB 154596
- Open following ports:
- source server >> target server
Port: 3725 TCP – data transfer - platespin server >> souce server
Port: SMB (TCP 139, TCP 445, UDP 137,UDP 138), 135 TCP/445, and RPC ports which you specified while made port limitation – default port range 5000-5100 TCP
- source server >> target server
Good luck, you’ll need it 🙂
