The following conditions may occur when upgrading clusters. Try\nto complete the cluster upgrade as noted with the condition.\n\nRecover admin, hybrid, and standalone cluster upgrades\n\nAdmin, hybrid, and standalone clusters are all upgraded with the [`bmctl upgrade`\ncommand](/kubernetes-engine/distributed-cloud/bare-metal/docs/how-to/upgrade).\n\nIf your upgrade doesn't complete successfully, check the following conditions\nand try the upgrade again.\n\n- `bmctl` fails to parse the config file due to a mistake. Fix the config file and rerun the command.\n- `bmctl` fails to bootstrap the temporary cluster. Retry the command.\n- the log files indicate that the upgrade failed a [preflight check](/kubernetes-engine/distributed-cloud/bare-metal/docs/installing/preflight). Correct the preflight condition, or force the upgrade.\n- the upgrade took too long (more than 30 minutes) or timed out. Retry the upgrade command.\n\nRecover user cluster upgrades\n\nUser clusters are [upgraded from an associated admin cluster](/kubernetes-engine/distributed-cloud/bare-metal/docs/how-to/upgrade)\nwith the `kubectl apply` command.\n\nIf your upgrade doesn't complete successfully, check the following conditions\nand try the upgrade again.\n\n- Preflight check failed. Check the preflight check log and fix the corresponding error.\n- You may need to construct a new preflight custom resource [following these instructions](/kubernetes-engine/distributed-cloud/bare-metal/docs/installing/preflight#re-enabling_preflight_checks) and apply it to the cluster. Check that the triggered preflight passes, and that the cluster reconciler picks up the latest passing state.\n\nWhat's next\n\nIf you need additional assistance, reach out to\n\n[Cloud Customer Care](/support-hub).\nYou can also see\n[Getting support](/kubernetes-engine/distributed-cloud/bare-metal/docs/getting-support) for more information about support resources, including the following:\n\n- [Requirements](/kubernetes-engine/distributed-cloud/bare-metal/docs/getting-support#intro-support) for opening a support case.\n- [Tools](/kubernetes-engine/distributed-cloud/bare-metal/docs/getting-support#support-tools) to help you troubleshoot, such as your environment configuration, logs, and metrics.\n- Supported [components](/kubernetes-engine/distributed-cloud/bare-metal/docs/getting-support#what-we-support)."]]
