Migrating from Installer-based SSMC deployment to SSMC appliance

SSMC is available only as a virtual appliance from 3.4 release onwards. If you intend to migrate from an earlier SSMC deployment (SSMC 3.2 to 3.3.1), use the HPE SSMC migration tool.

HPE SSMC migration tool is a separate installer available for Windows and Linux environments. Install and run the migration tool from the same machine or VM which currently hosts the older SSMC instance.

To allow inbound communication from a browser, SSMC uses inbound port 8443 (default).

CAUTION:

  • Migration changes related to SSMC 3.6 release: Before SSMC 3.6 release, you were using the migrated admin credentials to log in to the Administrator Console after the migration was successfully completed. From 3.6 release and later, use the appliance credentials to log in to the Administrator Console instead of the migrated admin credentials. Also, Clear Admin Credentials will not be supported for resetting the admin credentials.

  • Do not set administrator credentials or any credentials on SSMC appliance before migration. If you set the administrator credentials, then the migration fails. Migration service always verifies the credentials or settings on SSMC. If any configuration exists prior, then migration fails. The migration failure status will be notified to user.

  • When prompted by migration tool, use the same password you provided for ssmcadmin user while deploying SSMC appliance.

  • The SR reports stored in the custom path is stored in the directory /var/opt/hpe/ssmc/data/persist/scheduledreports/users/.

  • If you clear already defined administrator credentials and in case if you perform migration again, then the settings on the appliance will be modified.

The following table depicts the migrated and nonmigrated components by using HPE SSMC migration tool:

Migrated components

Nonmigrated components

SSMC administrator credentials

Logs

SSMC configured arrays and their credentials

SSMC port configuration (always 8443 in appliance)

SR reports

SR reports custom path

HPE 3PAR RMC configurations

 

CA-signed certificates

 

FIPS mode configuration

 
WARNING:

Migration might replace any CA-signed certificate that is configured at the target appliance. Hewlett Packard Enterprise recommends configuring CA certificate on the appliance only after the migration. If you configure CA-signed certificate in the appliance before migration, then you might have to configure CA certificate again.

To configure CA-signed certificates for SSMC, see Managing CA-signed certificates for SSMC.

HPE SSMC migration is a two-step process. In the first step, the SSMC configuration is migrated and the target appliance is usable, except for functionality of viewing previously generated SR reports. In the second step, the user is prompted to migrate SR reports. The SR reports migration is initiated once the user selects SR migration.

NOTE:

The SR reports migration might take longer time based on the cumulative size of reports. If this migration fails due to network disruption or reboot, rerun the migration tool. The SR reports migration resumes for those reports which were not migrated due to the failure.

If you migrate an SSMC 3.3 or 3.3.1 with FIPS mode enabled, during migration, the migration tool prompts you to enter the appliance certificate.

The HPE SSMC migration tool is available for Windows and Linux environments, and includes separate instructions for migration.

Prerequisites

  • Only administrator or root user can initiate migration.

  • Ensure that the appliance is reachable from the source SSMC machine.

  • Migration to SSMC 3.8 version can be done from SSMC 3.3 release onwards. Migration cannot be performed from versions prior to SSMC 3.3. If the SSMC being migrated is not at the minimum version required, you must upgrade SSMC before migration.

  • Ensure that the ssmcadmin user credentials are set before migrating to SSMC appliance.
