Upgrade Procedure

You must reset the disaster recovery configuration on both the active and the standby sites to stop the disaster recovery process and clean up the disaster recovery configuration from both the sites. You can upgrade the Junos Space Platform software at both the active and the standby sites at the time of deployment. Since the disaster recovery upgrade procedure is time consuming, we recommend you to reset the disaster recovery configuration and upgrade the sites to the required version.

The upgrade procedure comprises of the following tasks:

  1. Back up the Current Disaster Recovery Configuration

  2. Reset the Disaster Recovery Configuration

  3. Upgrade the Junos Space Network Management Platform and Application

  4. Configure and Perform Disaster Recovery

1. Back up the Current Disaster Recovery Configuration

Backup the current disaster recovery configuration on both the sites to refer the parameters when configuring the disaster recovery again after upgrade. Run the following command to create a backup for current configuration on both sites:

$ jmp-dr api v1 config --include role,failover,states,core,deviceManagement,mysql,pgsql,file,watchdog > /home/admin/dr-config.txt

Note:

Enter the following command in a separate shell prompt on the VIP nodes of both the sites to check log errors:

$tailf /var/log/jmp-geo/dr-cli-reset.log

2. Reset the Disaster Recovery Configuration

Reset the current disaster recovery configuration to ensure that both the active and the passive sites refer to the same parameters, when you configure the disaster recovery, post the upgrade.

Execute the following command to create a backup for the current configuration.

$ jmp-dr api v1 config --include role,failover,states,core,deviceManagement,mysql,pgsql,file,watchdog > /home/admin/dr-config.txt

Execute the following commands to reset disaster recovery on both sites running the jmp-dr reset commands on VIP nodes of both sites.

After executing this commands, the sites become standalone sites. Junos Space Platform comes up and you can access the UI from both the sites.

3. Upgrade the Junos Space Network Management Platform and Application

You can upgrade the Junos Space Platform and the application on both the active and the standby sites simultaneously, as both the sites are in standalone mode.

    2. Execute the following command in the VIP node of standby site to configure disaster recovery.
    Note:

    Ensure that you initialize the disaster recovery process on the standby site, only after the disaster recovery initialization is complete on the active site. For more information about configuring the disaster recovery process, see Configuring the Disaster Recovery Process Between an Active and a Standby Site.

  2. Execute the following command to start the disaster recovery process from the active site.
    Note:

    Execute the following command in the separate shell prompt on each of the VIP nodes of the site to check the logs for errors.
