Xos Firmware upgrade


Userlevel 1
Hi, We do most of our maintenance end of the year, and I going to upgrade the firmware on the switches, and Core, they are currently running Xos 12.5.4.5 and have a couple of new summits stack on 15.7.1.4, what will you recommend upgrade all of XoS to 15.7.1.4 or "jump" all of them to 16.1.2?

Thanks

p.s. I don't have a lot of maintenance windows during the year

Hi Karina,
Take a look at this thread: https://community.extremenetworks.com/extreme/topics/what-is-the-newest-firmware-version-for-the-bla...
And this article: https://gtacknowledge.extremenetworks.com/articles/Q_A/What-Is-The-Recommended-Release-of-EXOS-For-M...
The information there is more specific to the 8800 series, but the concepts still apply to all EXOS products.

Regarding the "recommended release" document, keep the following in mind.
Generally speaking, ExtremeXOS software version recommendations are based on the following criteria:
  • Recommended releases should have no open critical issues introduced in the respective version
  • Recommended releases should have been deployed in field for at least 3 months. As an exception, the latest release would be recommended if critical fixes affecting existing deployment were added to the release.
  • Internal SQA testing must be completed without encountering any new issues
  • Recommended releases should have been reviewed and accepted by Engineering Team Leads
When deploying any software release, customers should always review the Release Notes for known issues that pertain to features and technologies used in their network. Upgrades above these recommendations are suggested only to fix a specific known issue or to implement a required ExtremeXOS feature not included in the currently recommended release.

If you've got questions or want further advice, let us know!

Thanks,
-Drew
