ASR 9006. Upgrade from 4.3.4 to what

[pshadrin1]

Hi!

We have four ASR9006 (A9K-RSP440-TR) boxes. All of them have 4.3.4 version of XR. We want to upgrade them.

1. What new version of XR you recomended for out RSP? 

2. As i know, version 4.3.4 has porblem with old css certificate (CSCut52232). So, what method for upgrade XR you recomended: through install PIE or through ROMMON?

Trident cards are only supported until 5.3.4

Typhoon cards can run higher code

Tomahawk cards can run 64bit xr

without knowing what cards you have in the system it is difficult to say

64bit requirements

In general you can upgrade to the highest EMR release which is 642

Thanks

Release 6.2.3 or Release 6.3.3 are good choices as both are Extended Maintenance Releases.

6.3.3 was FCSed yesterday.

[pshadrin1]

What about 6.4.2?

[Syed Zaidi · Accepted solution]

I don't think with RSP440 , you can load 642 , so 633 will be the latest to deploy based on your show platform. Please have a look @ https://www.cisco.com/c/en/us/products/collateral/routers/asr-9000-series-aggregation-services-routers/eos-eol-notice-c51-737819.pdf

Thank you.

What method of installation do you recomended: through ROMMON or through IOS-XR cli?

[Syed Zaidi · Accepted solution]

As the delta is significant ( Skipping 5xx and going to last release of 63x ) , I recommend testing the upgrade first by upgrade method and if it fails , we can try turboboot ( if acceptable to the Customer for such a downtime ) before deploying it

FPD versions can sometimes become a gating factor and lab testing the upgrade can take care of it.

And as Bryan Garland suggested , please have a look at https://community.cisco.com/t5/service-providers-documents/ios-xr-release-strategy-and-deployment-recommendation/ta-p/3165422

Hello There



I looked into 642/RSP-440 and came to know that 642 is the last release supported on RSP 440 , so it is another option to consider

[pshadrin1]

Thanks a lot!
