Do you know it is possible to convert one Bank of America/FIA credit card to another without losing the credit score benefits of having a card with a history? I've got a Bank Americard which essentially gives me 1.5% cash back that was opened in 2008 and is my credit card with the second longest history. If I could change it into the Fidelity Investment Rewards Amex and somehow still have it look like I've had that line of credit since 2008, I'd switch. Both cards are issued by the credit card company that is now BofA/FIA/MBNA, so I'm hoping it can be done somehow. I have heard Amex allows you to convert cards without having it look like you closed one account and applied for new credit on the cards they issue (e.g., switching from HHonors Amex to the Surpass Amex), so there may be precedent in the industry.
