Retirement tax questions

@Opus 17

You mentioned, 

     You can then do a Roth conversion in 2022, and it won't be taxed ("backdoor Roth").  You can also do a new  backdoor Roth by making a 2022 non-deductible IRA contribution and then converting it.

 

Will I be able to do both in 2022 or only one or the other? And a new backdoor Roth will also be non-taxed?
