We wish to upgrade from 6.5.3 to the latest (7.2.4 at this time).
We have:
- Index Cluster Master
- Search head cluster (3 nodes)
- Index Cluster (3 nodes)
- Heavy forwarder (1 node)
- Configuration manager
- API collector
- Splunk CM (?)
From my reading of:
- https://docs.splunk.com/Documentation/Splunk/7.2.4/Indexer/Upgradeacluster
- https://docs.splunk.com/Documentation/Splunk/7.2.4/DistSearch/UpgradeaSHC
- https://docs.splunk.com/Documentation/Splunk/7.2.4/Installation/HowtoupgradeSplunk
It looks like:
- We will need to upgrade in 2 steps - say 6.5.3 to 7.0 and then 7.0 to 7.2.4
- I can perform a tiered upgrade:
1. Index Cluster Master
2. Search head cluster (member by member)
3. Index cluster (if I have correctly read this as the peer nodes)
4. Heavy forwarder
5. etc.
Is my reading correct?
