Compatibility between IOS-EX 17.9.5f and ROMmon 16.9(4r) on ASR1001-X

[AK7777]

Hi everyone,

I'm planning to upgrade the software on my Cisco ASR1001-X router.

I would like to confirm if IOS-XE version 17.9.5f is fully compatible with ROMmon version 16.9(4r).

Has anyone successfully used this combination in production or lab environment?
Are there any known issues or compatibility notes I should be aware of?

Thank you in advance!

hi @AK7777 as per the compatibility guide, 

IOS-XE 17.9.5f need minimum ROM 17.3(1r).

check the 'Table 4. Minimum and Recommended Release for ASR 1000 Series Routers' in below document.
