Vanguard move from mutual fund account to brokerage account

By "different numbers", are you referring to "account numbers"? If not, what?

lf you are just converting old Vanguard mutual fund accounts to a new(er) Vanguard brokerage accounts; after the conversion, the holdings in each new Brokerage account should exactly equal the final holdings in each corresponding old mutual fund account. I assume you have already told Vanguard to make the conversion at their end; so your old Vanguard mutual fund accounts are now closed and those old mutual-fund account holdings at Vanguard are now in your new Vanguard brokerage accounts.

1.) Backup your Quicken file. 2.) Use the Quicken "Add Account" process to create a new Quicken Vanguard brokerage account for each old Vanguard mutual fund account. 3.) Delete any downloaded transactions in the new Quicken Vanguard brokerage accounts that pertain to the transfer from the old mutual fund accounts (likely Add shares transactions - which will probably not have the correct cost basis). 4.) In each of the old Quicken mutual fund accounts, enter a "Shares transferred between accounts" transaction (for "All shares") and name the appropriate new Quicken brokerage account as the TO account. 5.) Verify that your holdings (including cost basis) are the same in the new Quicken Vanguard brokerage accounts as they were in the old Quicken Vanguard mutual fund accounts. 6.) Verify that the holdings in your new Quicken Vanguard brokerage accounts are the same as they are at Vanguard (in the Account Actions drop down in the new Vanguard accounts, select "Reconcile shares"). [Note: there are users who prefer to do as you suggested: deactivate each old Quicken account, then re-activate each one (probably removing the account numbers from the old Quicken accounts while they are deactivated). That approach should work and it is probably simpler, but I prefer the approach I suggested because it more closely reflects what happened in the real world.]

thanks for your help
