RickO’s method is the easiest. You just need one transaction to record the sum of everything older than one year, since everything they are all long term gains.If you really want to preserve the entire transaction history, you could try this, which is a lot trickier, and I’m not really sure you can do it this way anymore in QM2018.0. Make a complete backup, in case you need to start over!1. Export the transactions from the mutual fund account to a QIF file.2.use a text editor (I use TextWrangler) to edit that file, changing the account name to match your Brokerage account and save it as text, but still with the .qif extension. I’d use a different name for this modified file.3. With your brokerage account open, Import the modified transactions. Do they all show up in the right place?4.when you’re confident every transaction has been moved, delete the now redundant mutual fund account.Good luck!
