I have to change all the duplicant CID's for new software for project tracking. Bacically I'm exporting to a CSV file, and then they are importing that file into the estimating software. For this to get mapped correctly the CID's have to all be different.

So I was asked if we could do this for previous jobs, and I have not a clue if you can since they have a different set of CID's attached to them.

Any thoughts?
