Compatibility between forwarders and Splunk Enterprise indexers
The following table shows which versions of forwarder and indexer are compatible. A best practice is to use indexers with versions that are the same or higher than forwarder versions.
Determine forwarder-indexer compatibility
The following table shows the versions of forwarder and indexer that can be used together. As a best practice, forwarders should communicate with indexers that are the same or higher version. If the forwarder version you want to use is not in this table, then there is no support for it. See Product Supported Version Timelines on splunk.com.
If you are looking for the Splunk Cloud forwarder compatibility list, see Supported Forwarder Versions in the Splunk Cloud Service Description manual.
- E - Events. This version of forwarder can send event data to the corresponding version of indexer.
- M - Metrics. This version of forwarder can send both event data and metrics data to the corresponding version of indexer.
- S - SSL change required. This version of forwarder can send event data to this version of indexer only if you change the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) version and cipher suite on the forwarder.

The table provides version 6.x compatibility for universal forwarders only. Version 6.x forwarders are compatible with higher versions of indexer, but Splunk will not provide support for version 6.0.x - 6.2.x forwarders. Version 6.3.x - 6.6.x universal forwarders have limited support through June 4, 2021.
