Am trying to upgrade many UFs & HFs to 8.2.2. Any issues to watch for? Also, what should be the order? Should the Splunk servers (instances) be upgraded first or last? Thanks a million.
Be aware that 8.2.2.1 is out and, IIRC, addresses a problem with 8.2.2 on Windows.
The usual upgrade order is LM, CM, SH, Idx, SHC Deployer, forwarders.
