Cisco ASR 9010 - RSP Compatibility

[aridy]

Hi,

I have a Cisco ASR9010 Router running only with one RSP card.

Now I want to add another one to have a redundant system, but I want to know what happens if the card that I will add has a newer IOS XR version compared with existing one.

Do you have any previous experience, or can you redirect me to some Cisco material explaining this?

Thanks,

Aridy

RSP redundancy (both RSPs must be the same version - and same model as you have aleardy.)

some reference guide attached.
