I recently converted VTSAX to VTI. I used the Mutual Fund Conversion transaction in Quicken Windows Premier R61.21. The resulting entries for purchase price and cost made no sense at all, though the final share count matched Vanguard's. Each transaction was so crazy that I won't go into the details. Thankfully I have learned to have a backup before trying such global conversions. The transactions in my Vanguard brokerage account go back to 2005 and were converted from a Vanguard mutual fund account to a brokerage account somewhere along the way, so the old original cost data is long gone. I DO have a spreadsheet download of Vanguard's calculated cost data and transactions for the VTI conversion back to 2005 when the brokerage account started. I am thinking I can go back and simply enter the transactions from the start (20025) as VTI and delete the VTSAX transactions? It is a lot of work, but I can't see another way to complete the task. Note: I don't use Quicken for tax purposes but mainly for investment tracking and performance. Is there an easier way?
