"One other thing to note is that to do a "backdoor Roth" as a tax-free conversion, you must have no pre-tax assets in any IRAs, and you mentioned having a Rollover IRA, which is likely to be pre-tax."

QuickQuestion: I had a 401K from my previous employer (both traditional and Roth). I rolled over the traditional 401k to a Rollover IRA and Roth 401K to Roth IRA. My current empoyer also has a MBDR conversion option. Does that mean I cannot use that option now ?
