### 12.2.2. Preparing to Upgrade from EKM 18.0 or 18.1

Before you upgrade an EKM 18.0 or 18.1 server to EKM 18.2, you must back up the EKM 18.0 or 18.1 server, and then stop it. Please complete the steps below before proceeding with the upgrade.

1. Perform a full backup of the EKM 18.0 or 18.1 server. Refer to the Backing Up and Restoring EKM chapter in the EKM 18.0 or 18.1 Administration Guide for more information. If the upgrade procedure fails, you may need to recover the EKM 18.0 or 18.1 server from backup.

   Important: Failure to perform a full backup of EKM 18.0 or 18.1 according to the instructions in the EKM 18.0 or 18.1 Administration Guide could result in unrecoverable loss of data.

2. Stop the existing EKM 18.0 or 18.1 server. See the EKM 18.0 or 18.1 documentation for specific instructions on stopping the EKM server.

3. Stop the cluster database server (for example, the MySQL database server if that is what you are using).

4. If EKM is registered to run as a service, unregister the EKM services. See the EKM 18.0 or 18.1 documentation for specific instructions on registering and unregistering EKM services.
