Multi-Cluster Version Support
Multi-Cluster Version Support in LogScale requires running the same version across all clusters due to protocol compatibility requirements between systems sharing Multi-Cluster search information.
The multi-cluster protocol is not compatible across different versions of LogScale. Compatibility depends on the underlying protocol used for sharing Multi-Cluster search information between systems.
Important
In general, you should run the same (major and minor) version of LogScale on all clusters.
Multi-cluster search is available when the minimum compatible version matches the cluster where the view was created. Two versions are compatible if they have the same minimum compatible version.
Multi-Cluster Compatibility Across Versions
The multi-cluster protocol is compatible across versions of LogScale provided that the federated clusters are within one LogScale LTS version. The implementation checks that the versions match and data may be omitted from any remote clusters running a different version (that is, a version other than the given LTS version) from the federating cluster.
Two versions are compatible if they're both within the same LogScale LTS version. This means that compatibility is ensured when upgrading from one LTS version to the next one. Conversely, LogScale does not guarantee compatibility if there is an upgrade that skips one or more LTS versions.
