Not exactly. You still have to follow the ordering rules for distributions that are detailed in IRS Pub 590-B (https://www.irs.gov/pub/irs-pdf/p590b.pdf) Those rules require you to take out contributions first, and then, beginng with the oldest year, take out coversions by year. You will need to document this all on Form 8606, which is also required to be filed each year you do a conversion. It will be very useful to you to get the last Form 8606 you filed. If you have not filed a Form 8606, you need to file one that documents the connversions prior to taking any early distributions.
