Oracle DB Clone and New IP

We clone our production to PTE (Production Test) once in a while and sanitize the data. As far as I’m aware, the DBA runs the clone command from PTE, this goes over 1Gb firewall and can take quite some time.

PTE is a VM, could I add a new NIC on the Production VLAN to the PTE host so it would copy bypassing the firewall? (Bypassing gives them 10Gb network). Any issues just adding a NIC to PTE without affecting the Oracle install, I don’t want anyone to connect on that temporary IP, just trying to speed things up.
