Roamio OTA

Can the Roamio OTA stream shows from other DVRs? (bolt+). My recent Roamio Pro failure has me thinking of disaster recovery options. I'm thinking about buying a roamio OTA and putting it on my spare TV. If my new bolt + suffers a failure, I can switch the minis to the roamio OTA (?).

What I am wondering is if the roamio OTA can stream from the bolt +?

Thanks
