Hi @EvansB,

the general rule for upgrading is:

  • Search Heads must have a greater version than Indexers,
  • Indexers must have a greater version than connected Heavy Forwarders and Universal Forwarders,
  • Heavy Forwarders must have a greater version than connected Universal Forwarders.

The Step by step procedure depends on your architecture: if you have a Search head Cluster or an Indexer Cluster, there is a prececence in activities.

Then another relevant factor is the starting version: for more infos see at https://docs.splunk.com/Documentation/Splunk/8.2.4/Installation/HowtoupgradeSplunk

For Heavy Forwarders, you have only to perform a simple upgrade, eventually backing up the installation folder.

Ciao.

Giuseppe
