We are upgrading our Splunk Indexer from 6.4.3 to 7.1.2 (via 6.5). Our forwarders are running a mixture of 6.2.4 and 6.4.3 and are NOT using SSL.
Then I noticed this compatibility matrix for the UFs: http://docs.splunk.com/Documentation/Forwarder/7.1.2/Forwarder/Compatibilitybetweenforwardersandindexers
If I read this correctly, does this mean we must enable/configure SSL on our 6.4.3 UFs before we upgrade? Or will we still be able to send data to the 7.1.2 indexer without SSL from the older UFs?
Thanks!
