Hello@brhutch
Thank you for posting in the Community today. Indeed, there are a few ways to handle this situation and it all comes down to what you prefer.
Yes, you can set up the current accounts with the financial institution and proceed to download transactions. Though, depending on how the current accounts were created, this may cause an issue with formatting.
It may be best to create new accounts and set those up for transaction downloads to be sure that the many years of historical data from the current files are not changed.
If you would like to see what both scenarios would look like and how it would function, you can create a copy of your data file to test with. That way you know that your original work and data is safe while you experiment with the options.
Thank you
