Automation Suite Installation Guide

Performing Node Maintenance
There are scenarios where you may want to perform a node maintenance activity, such as the following:
- When applying security patches;
- When performing an operating system upgrade;
- When changing any network configuration;
- When performing any other activity that your organization mandates.
While performing node maintenance operations, it is possible that you may accidentally break the cluster. To avoid any adverse situation, follow the guidance provided here.
Note:
- UiPath does not provide guidance on how to perform node maintenance activities. You must contact your IT team for this.
- The following guidelines only provide instructions on the steps you must take before and after the node maintenance operation, to ensure the cluster is healthy.
- It is good practice to perform node maintenance activities on one node at a time.
