- | ===== Patching Best Practices ===== | ||
- | |||
- | * If you want to familiarise yourself with the changes introduced by a patch prior to deploying the patch to production, install it first in a non-production environment and test it there. | ||
- | * Patch your system during a service window when users are not permitted to use the system. | ||
- | * During the service window and prior to patching the system, backup the appliance itself and, if the database is external, backup the database as well. (If you have a a multi-node (HA) system, it is only necessary to back up one node.) | ||
- | * Confirm that the system is working correctly after applying the patch and prior to ending the service window. | ||
- | * If you are unable to confirm that the patched system is working properly, contact SME Support or roll back the patch prior to ending the service window. (Roll-back instructions are provided later in this document.) | ||
