I easily changed my Bank of America Platinum card to a World Points card last December. One thing--if you currently have a decent APR on your account, make certain that the product change also has the same, or a more favorable APR. About 3 years ago, I wanted to change my Bank of America card to a different one, and the regular customer service rep was anxious to change it immediately. I told her I wanted to think about it first. Later, I talked to a Bank of America "Retention Department" rep. She discouraged me from changing my card, telling me that if I changed my account to the other card that I was thinking about, my APR would go from 7.9% to something awful, like around 16%. The first rep didn't tell me about that horrendous APR.
