That is what our company did. 
We had a computer that the new version had not been installed on. I always back up all of our clients information from all data paths including our company at the end of the year.

I downloaded the 2024/2025 version on this computer, restored our companies data from my December back up, re-entered transactions. We are all having to use this one computer to do our billings and payments. Pain in the fanny but at least we have good totals for our clients and statements that are correct.
