[Gvenugopal2711]

Hi

recently i have upgraded splunk indexers from 4.2.3 to 5.0.6. splunk forwarders were still running on 4.2.3(i know forwarders still support 5.0.6 backword compatible).

but how long we run this forwarders on older version.

Thanks

I had 4.1.8 forwarders running for months against my 6.1.2 indexers without issue. But when I submitted an issue with a 4.n forwarder, Support wouldn't help because of the 4.n version. So I did the upgrade in three steps. 4.2, 5.0, 6.1.2. It was so easy I linked the 3 individual scripts so that one would call the other. The remaining servers were upgraded in minutes. Why wait?
