Synchroize A900-RSP3C-200-S or install image on backup RP

[PK99]

Current set up is A903 with 2 X RSP3C-200-S.  RP0 has image but RP1 has older image.  Anyway to make them sync like ASR9000?

Can you post more information about what version on both the devices?

you can not have 2 different versions, when the failover occurs some features not supported on the old version may not work.

so always make it both the same version.

follow the below guide to upgrade : (this for reference only - depends on the version you use steps:)

RP0 is running

Cisco IOS XE Software, Version 03.18.04.SP.156-2.SP4-ext

RP1 is running

Cisco IOS XE Software, Version 03.18.04.SP.156-2.SP2-ext

I noticed that RP1 has 156-2-SP2.bin file in the bootflash while RP0 does not.

Is there a way to make RP1 Sync with RP0?
