|Title||Distributed environments: Improve config synchronization|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Compatible - no manual interaction needed|
Synchronizing configurations between the central and remote sites has taken too much time in the past because the entire configuration was always synchronized. Even files that are still present on the remote site were completely synchronized, which led to increased computing effort, traffic and runtime.
This mechanism has now been replaced by an incremental mechanism. Before each synchronization, the system determines which files already exist on the remote site. Only those files are synchronized that differ from the central site.
For the migration from Checkmk 1.6 to 1.7 the change is compatible. Both central 1.6 sites can communicate with remote 1.7 sites and 1.7 central sites can communicate with 1.6 remote sites. Mixed environments should only be used for migration purposes. In such a scenario, the previous synchronization mechanism is used. After 1.7 this compatibility mode will be removed.
