Configuring the Source Appliances

To migrate data from an existing (source) appliance to a new (destination) appliance, you must configure data migration on the source appliance (10.0.20.31, in this example) and then on the new appliance (10.0.20.33).
Note: When migrating data for an HA pair, the source appliance being configured for failover satisfies the requirement. You do not need to disable failover and enable data migration on the source appliance.

Prerequisites

If you are migrating data from a LogLogic MX Appliance to a LogLogic LX Appliance, you must run the migration script to match the number of maximum supported devices between LogLogic MX Appliance and LogLogic LX Appliance before actual migration starts. To run the migration script, perform the following steps:
  1. Login to the LogLogic MX Appliance through the CLI, as a toor user.
  2. Run the following command from the /loglogic/scripts directory: 
    sh prep_migration_mx2lx
  3. Type yes to continue.

Procedure

  1. Log in to the source appliance through the CLI as a root user, using either a serial console or a remote SSH connection.
  2. Enable data migration on the source appliance: 
    > set data migration
  3. Enter the IP address of the other appliance (for example, 10.0.20.33).
  4. When the appliance prompts you to identify the direction of data migration, enter 1. 
    Select the data migration path
0) Do not setup data migration
1) This Appliance -> 10.0.20.33
2) 10.0.20.33 -> This Appliance
    The appliance warns you that changes have not been saved.
  5. Save the changes to apply the new configuration and restart the software: 
    > save

    The appliance processes the changes, displaying the steps as they occur, and then informs you when it is done.

    Note: If you have multiple IP addresses you are prompted to select the IP to use for High Availability.
  6. Log on to the source appliance through the GUI web server.
  7. Verify the appliance is correctly receiving and processing logs.
    The dashboard reports an HA error because the new appliance is not yet configured.
