Are there any docs about SHC upgrading path.

[Shuhei052492]

Hello,

I would like to know the upgrading order about SHC and IDX.
I saw the following doc and answer.
https://docs.splunk.com/Documentation/Splunk/7.3.1/DistSearch/UpgradeaSHC
https://docs.splunk.com/Documentation/Splunk/7.3.1/DistSearch/Distsearchsystemrequirements

As the result, I have understood the following upgrading order.
1. Upgrade each masters(LM-->CM)
2. Stop members and run the mantainance mode and
3. Upgrade search head node
4. Upgrade deployer node
5. Upgrade peer node
6. start member and master
7. Upgrade rest node like DS UF and so on...

Is this upgrading order right?
I saw the following answers the order is different. The answers mention to upgrade peers before SHs.
I can not upgrade all node in a whole day, because of test.

I appreciate to give how to upgrade the SHC and IDC environment.

Best regards,

Hi @Shuhei052492,

The upgrade order you mentioned is correct.

You can use the following document to correctly plan and execute your upgrade :
https://docs.splunk.com/images/d/d3/Splunk_upgrade_order_of_ops.pdf

It contains all the pre-requisites, the upgrade order and any additional checks required to ensure a successful upgrade.

Let me know if that helps.

Cheers,
David
