Generally, only one of these distributions is eligible for rollover. Rolling over both of these IRA distributions (one traditional and one Roth) would be a violation of the one-rollover-per-12-months limitation. Tax consequences are likely minimized by rollover over some or all of the traditional IRA distribution rather than the Roth IRA distribution.
However, you can roll over the Roth IRA distribution and also do a Roth conversion of some or all of the distribution from the traditional IRA. Roth conversions are disregarded with respect to the one-rollover-per-12-months limitation. The Roth conversion would be taxable, but it would avoid any early-distribution penalty if you would otherwise be subject to such penalty. You would also have the long-term benefit that future gains on the amount converted would be tax free once your Roth IRAs are qualified.
