Is it possible to have two Modbus map in one PLC?

I have a PLC that already have a big map (3000 registers). I have a PC software to talk to the PLC.

Now the customer want to re-arrange the registers. I wonder whether I can map the same logic to a second map. example, to my software, Modbus ID 1: 40001 is to move a valve, and customer want to move to 40100. so is there a way to do the same thing to both ID 1:40001, and ID2:40100?

This is a general question. if you need to know my PLC underlining programming language, I have to take a look.

This should not be a problem at all. You need to provide more information though if you want how this is to be done.

The problem is actually if for example you need to move 40001 to 40100 and 40100 to 40200, then you need to be sure that the 40100 was moved to 40200 before you overwrite it, as I understand, this is not an issue for you, you are moving to an entire new area. If so, then you are good to go, provide PLC type, software and version, etc. to get a precise answer
