Merge two credit card accounts

Not the most elegant of solutions as transfers to the CC account (e.g., payments) would then point to invalid account.

No, that isn't correct.
Example:


Create new account:


Now back to the original credit card and copy the transactions to the new one.


Notice that the payment from checking account (a transfer) is just fine.
I do have to deal with the duplicate opening balance, and of course if this was an actual merge of two accounts, I would have to take care not to transfer duplicate transactions.  But as you can see the transfers to other accounts are just fine.

Note that the real process would be to remove the opening balance from the new account and any duplicate transactions in it before copying all the transactions (including the opening balance transaction) from the old to the new.  Once that is done, remove the old account.

Hi @Frankx --- in my case the financial institution re-issued a credit card with a different number after some sketchy activity. The solution put forward by Tech Support was as follows:
1) Edit old account to Deactivate Online Services
2) Edit account details to delete Account Number from General Tab
3) Add NEW last four digits (at least in my case) in Account Number Field
4) Add NEW account [Tools --> Add account]
5) Go to your financial institution -- hit next
6) Login to financial institution and authorize access -- select your account with new number
7) LINK to the old account (i.e. do NOT add a new account, link to the old account
8) Hit next and the magic happens....you save all your old data and are now accessing the new account -- all in the same register. In my case the register goes back several years, nearly a decade in fact.

This solution worked for me YMMV. I did have to do some cleanup of a few duplicates

Full Disclosure: I had been adding transactions to the old account for a few MONTHS without noticing that the one step update was not clearing new transactions...they were going to a new account created when I changed CC numbers. Severe pilot error on my part.
