Hi, I am an accountant, not an IT professional. We have a situation at my company where we need to change the account numbers for a group of accounts. We need to move all history and current activity associated with these accounts to the new account number. I have explored using the "move" function in the Mass Modify Chart of Accounts window, but this utility only works if there is no history or current activity in the accounts that you want to move. Does anyone have any suggestions? Thanks.
