OS upgrade

[rahulhari88]

Hi All ,

We have 1 indexer, 1 SH and 1 DS . We are  planning for an OS upgrade (OS RHEL 6 to OL 7)  .All the these devices are on the Cloud . Can someone help me what are the steps to be taken from Splunk perspective during this upgrade . What are the checks to be done and is there any pattern like first indexer , then DS and then SH to be followed .

What to do in a fail over .

Splunk is not getting upgraded as of now . We are keeping the same splunk version 7.3.

I have already read this article 

 https://community.splunk.com/t5/Installation/What-s-the-order-of-operations-for-upgrading-Splunk-Ent... 

but i am not upgrading splunk here .

Hi @rahulhari88,

there aren't special requirements for your operation, you can follow the order you like in upgrade.

Your Splunk 7.3.0 is compatible with every Linux with 3.x and 4.x Kernel version (https://docs.splunk.com/Documentation/Splunk/7.3.0/Installation/Systemrequirements).

Anyway, take in attention to upgrade as soon as possible also Splunk.

Ciao.
