Create a new Sheet for New Business but Keep Previous Categories

I have a previous “Sheet” with all my categories from a business partnership. We dissolved the partnership, and winding down the bank and credit card accounts. I have re-started business under new name and new bank accounts and credit cards. I want to create a new Google Sheet, but keep all the categories I have, just want the data feed to be from my new accounts going forward. How can I do this?

I’d probably create the new Google spreadsheet through the Tiller Console and copy-paste-values-only old categories to new categories.

I wouldn’t attempt copying the entire Categories sheet and things like renaming sheets, because that will likely break formulas and have them referencing the wrong Categories sheet.
