You can program a port without the DLC present or if possible do a move command. A tech with Mitel programming experience should have no problems with your scenario unless the DLCs are damaged due to the corrosion you found.

The most helpful (best practice) thing to do is a cut sheet with all info on the current DLCs including physical location on terminal blocks and then the same info from where the DLCs will be relocated along with corresponding physical location on the terminal blocks.
