Compatibility between forwarders and indexers
Following are the specific version compatibility restrictions between forwarders and their receiving indexers. For best results, ensure that the version of the indexers is the same or higher than the version of the forwarders from which they receive data.
- A forwarder that is version 6.0 or later can send data to an indexer that is version 5.0 or later.
- An indexer that is version 6.0 can receive data from a forwarder that is version 4.3 or later.
The following features are available only if both indexers and forwarders are at version 6.x or higher:
- Dynamic file headers.
- Forwarding of structured data.
- Timezone transmission by the forwarder. Additionally, forwarders do not maintain the timezone transmission feature across intermediate forwarding tiers when those tiers consist solely of light or universal forwarders.
