I have always added transactions to my Quicken investment accounts manually. I don't use One Step Update. I have searched the community posts for the best method to transition my Vanguard mutual fund accounts to my new Vanguard brokerage account, but they all seem to use the One Step Update method. Is there a simple way to to it manually? I have many years worth of transactions in each of my mutual fund accounts.
I'm just a little bit scared to use the One Step Update method since I'm not familiar with it. Just wondering whether anyone has done it the other way. Thanks!
