Most of the VMs - NAC, XMC and Analytics run on Ubuntu . Is there a guide to carrying out the OS updates i.e. things to do or Not do etc ?&nbsp; We have had issues in the past where the SNMP configs have been overwritten and broken things so we are cautious on how to proceed. I have had a look but I cant see anything related to this but please point me if I'm missing it.&nbsp;<BR /><BR />Many Thanks Tue, 19 Oct 2021 13:49:02 GMT https://community.extremenetworks.com/t5/security-access-control/extreme-vm-host-os-udating/m-p/74732#M29 graemedench 2021-10-19T13:49:02Z https://community.extremenetworks.com/t5/security-access-control/extreme-vm-host-os-udating/m-p/74733#M30 Our general GTAC KB article on the in's and out's of upgrading the XMC portfolio can be found @ <A href="https://extremeportal.force.com/ExtrArticleDetail?an=000082371" target="_blank" rel="noopener">HOW TO Guide to Upgrading Extreme Management Center, Extreme Control and Extreme Analytics</A>. ​<BR /><BR />The general process to upgrade remains the same to use the .bin image to upgrade a current deployment in place.
