Probably the easiest way is just to rename the Investor Shares funds to Admiral Shares fund.

That definitely is a clunky workaround to make sure that both current and historical data are accurate considering that the Windows version has a "convert" function, but it did work. I recorded the outgoing Investor Shares as a "Remove Shares" transaction (not "Sell") on the date of the conversion. Then I recorded each Admiral Shares lot as an "Add Shares" transaction (not "Buy"), which let me set the transaction date to the date of the conversion and input a separate "date acquired" for each lot so that the historical data is all there.
