Cisco Prime Optical High Availability Installation Guide, 10.5

Upgrading Cisco Prime Optical in an High Availability Environment Using the Data Migrator Wizard

---

This chapter describes how to use the Cisco Prime Optical 10.5 Data Migrator wizard to migrate select data from CTM R8.5 or later to Prime Optical 10.5. With the wizard, you can migrate a subset of an existing database to a newly installed Prime Optical 10.5 server.

The following are the benefits and limitations of the Data Migrator wizard:

• Reduces the migration time and provides a safer, easier migration.
• Lets you migrate the following data:

– Core tables and database pruning policy information.

– Service states and configurations, including CORBA and SNMP gateway states and configurations.

– Users, user profile information, and CORBA and SNMP gateway users.

– (Optional) Managed NEs, NE logical grouping information, network partition information, security information to authenticate to nodes, Domain Explorer and Subnetwork Explorer map coordinates, basic NE service configuration, and PM service states.

– (Optional) Manual links and Layer 1 circuits with user data.

– (Optional) VLAN customer-related information, Layer 2 topologies, and QoS templates.

– (Optional) Alarm Log Data

• Does not migrate PM data.

As the root user, install and run the tool on the same server where the Prime Optical database is installed.

The tool prepares a newly installed Prime Optical 10.5 server to use the data as used in the earlier server.

Caution You cannot migrate and preserve your entire database. You can only migrate a subset of your database by using the Data Migrator wizard.

Note In the bottom right corner of the wizard screens, the memory footprint progress bar shows the rate of available memory compared to the allocated memory; for example: “Available: x MB of y MB.” The “Request garbage collection” tool lets you free up memory when the amount of data is greater than what is expected, and the running task is taking too long to complete.
