Old Apple ID not valid

My Apple ID is no longer valid and I have a new one. How do I remove old one from my MAC?

What do you mean by not valid? If you can't sign out of the old Apple ID so that you can sign in with the new ID, do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart). Run Disk Utility/First Aid. Reformat the drive using Disk Utility/Erase. Use Mac OS Extended (Journaled), then click the Option button, and select GUID. Quit Disk Utility, then re-install the OS.
