Hi All
I have two splunk clusters. Each cluster has 2 sites
**Cluster 1 Site 1:** 3 Search Head, License Master, Index cluster master, 4 indexer, Deployment server, Search Head deployer/HF2, and HF1
**Cluster 1 Site 2:** 4 indexer, Deployment server, Warm Standby License Master, Warm Standby indexer cluster master, Search Head deployer/HF2, and HF1 (No search head in site 2)
**Cluster 2 Site 1:** Index cluster master, 4 indexer, Deployment server, HF2, and HF1
**Cluster 2 Site 2:** 4 indexer, Deployment server, HF2, and HF1
I am working on upgrading from 7.1.0 to 7.2.7. What is the sequence of upgrade?
is each cluster upgrade independently? if so, can I follow this procedure? https://docs.splunk.com/Documentation/Splunk/7.2.7/Indexer/Upgradeacluster
1. Upgrade cluster 1
2. Make sure all working (all host up, SF and RF are met)
3. Upgrade cluster 2
4. Make sure all working(all host up, SF and RF are met)
Do I have to change the index.conf of the default stanza after step 14?
