Combining American Express accounts
I have 10+ years of American Express transactions saved in Quicken.
AmEx recently issued me a new card with a different number due to suspected fraud. I deactivated/reactivated the existing AmEx account in Quicken with no problem, and downloaded transactions on the new card. However, those transactions are in a different (new) credit card account in Quicken.
I would like to have a single AmEx credit card account and, given the volume of data, it seems easiest to keep using the old one. How do I upload transactions on the new card to the old acount?
