RBR50 firmware update

[JoeRo]

Have an Orbi system (router + 1 satellite) that is still at firmware version v1.2.0.6.

I understand that to get current, I will need to do multiple updates - can't just go to the latest.  I also appreciate that there are a number of other prior entries on this subject, but none seem to be current.

Does anyone know which set of firmware versions I will need to install to get current on this?

Thanks!

Start with v2.0.0.74 on the RBS an RBR first, apply the RBS first then RBR lastly. Then you can go directly to latest on the RBS. However for the RBR, you'll need v212 next, then you can go to the latest. There are two choices for latest FW:
