Your Roth IRAs are already qualified since you are over age 59½ and you made your first contribution to a Roth IRA more than 5 years ago. This means that ANY regular distribution from your Roth IRAs is a qualified distribution, including any distribution of funds moved from your Roth 401(k) to the Roth IRA, tax and penalty free. Qualification of the Roth 401(k) is irrelevant to whether distributions from your Roth IRA are qualified distributions.
If you take a distribution from the Roth 401(k) and do not roll it over to a Roth IRA, because you have not met the 5-year holding requirement for distributions from the Roth 401(k) to be qualified distributions, some portion of the distribution from the Roth 401(k) would be taxable. But simply rolling all of that distribution over to the Roth IRA and then taking a distribution from the Roth IRA means that nothing will be taxable. You would want to avoid mandatory tax withholding on the otherwise taxable portion of the distribution from the Roth 401(k) by requesting a direct rollover to the Roth IRA where the funds are paid directly to your Roth IRA, not to you personally.
