 Before upgrading, make sure to read the [general upgrade guidelines](https://docs.kubermatic.com/kubermatic/v2.25/installation/upgrading/). Consider tweaking `seedControllerManager.maximumParallelReconciles` to ensure user cluster reconciliations will not cause resource exhaustion on seed clusters. A [full upgrade guide is available from the official documentation](https://docs.kubermatic.com/kubermatic/v2.25/installation/upgrading/upgrade-from-2.24-to-2.25/).
