Hello @teamp3,

 
Thank you for keeping in touch with us about merging bank accounts. Allow me to chime in and provide additional information regarding the process in QuickBooks Online.

The system moves all the data into the one you want to keep and removes the duplicate when you merge accounts. Our recommendation will depend on which one you prefer to retain and continue using in QuickBooks.

If you want to continue using the account connected to bank feeds, merge the old bank account. The merging process depends on your preference in managing the chart of accounts.

You can still link the old one to online banking if you prefer to retain it. Make sure to choose the existing old account when connecting the account to bank feeds to avoid duplicates.

Also, did you know that aside from merging accounts, you can also combine customers or vendors? I've attached a link you can visit to know more about the detailed steps: Merge duplicate accounts, customers, and vendors in QuickBooks Online.

Add a response below if you have more questions about banking or merging accounts. I'll be around to lend a hand.
