VLAN Translation

Not a network guy so forgive me. I have a situation where a customer has VLANs on a server that do not match the VLAN ID's of the switches. No idea why it was setup this way, but it's worked for 5+ years. Now, we are doing hardware refresh, and the method of migrating servers needs the VLAN numbers to stay the same on the source and target system. Here's the catch. Source servers have more network ports available than target servers, and switch ports are set to access mode (no VLAN tagging). Since new, target servers don't have enough physical ports to accommodate the same setup, we need to use VLAN tagging. The network guys didn't know how to accommodate this since VLAN numbers are mismatches on servers and switches. One of them just found out about VLAN Translation capability of Cisco switches, but they are reluctant to implement because they claim it is "not widely used in the industry". Can anyone verify or negate that claim? Thanks!
