Cisco ASR IOS XR 6.6.3 to 7.7.2

[uni1389]

Hello Team, 

We want to upgrade 4 X ASR9010 IOS XR 6.6.3 ( 64Bit ) to 7.7.2 . Being new to IOS XR wants to get some clarification:-

1. IOS XR 6.6.3-7.7.2 should be one step upgrade . or should we upgrade first 7.1 and then 7.7.2. 

2. Do we have some upgrade procedure documents. 

Thanks for all in advance for your short feedback. 

With Regards,

Hello Balaji, 

Thanks for your update. I have already go through these documents. The question is for me :-

Do we need two step IOS XR Upgrade or single Step Upgrade from 6.6.3-7.7.2 IOS XR. 

Thanks for you feedback.

you can directly upgrade, sometimes requiring an SMU upgrade look at the upgrade document.

if you have access download the document : have steps and suggestions

Cisco ASR9000 64-BIT IOS XR Software Upgrade/Downgrade docs. ASR9K-x64-docs-7.7.2.tar

Note : 7.7.2 MD release, cisco 5* still 7.5.2

Every software download has a docs download that tells you the supported upgrades. You will need multiple upgrades for 6.6.3 64-bit to 7.7.2.
