## Migrating KMC Server

Prerequisites

If the KMC server is integrated with RSA Key Manager, both the KMC and RSA Key Manager must be synchronized. If a KMC server is removed to purge all the keys, follow the required procedures to purge all the keys first before you uninstall the KMC server. This ensures that the keys in the RSA Key Manager are also purged.

Restrictions

The migrating of the KMC server is only applicable for SME Tape. For SME Disk, there is no RSA key manager support.

Detailed Steps

To migrate a KMC server, follow these steps:

1. Migrate all keys to the new KMC server. Refer to the backup and restore procedures outlined in “Database Backup and Restore Operations”.

2. After restoring the database, install DCNM-SAN in the new KMC server and point the DCNM-SAN to the database. This ensures that all the keys are maintained across the KMC migration.

3. Update the cluster with the new KMC server details when the new KMC server is active.

a. Go to the DCNM-SAN Web Client and click the SME tab.

b. Select the cluster. The cluster details page displays.

c. Click Modify and choose the new KMC server.

If the KMC server is integrated with RSA Key Manager, modify the settings and select the RKM server.

4. Uninstall the DCNM-SAN server instance of the previous KMC server. This removes the previous KMC server.
