This chapter illustrates the approach to migrate an existing airgap server already setup in Telco Cloud Automation 2.3.x or earlier releases to Telco Cloud Automation 3.0.0 airgap server deployed via OVA.

Follow steps below to execute the migration:

  1. Take a snapshot of the existing older version airgap server.
  2. Backup the certificate, IP address, and FQDN of the existing airgap server.
  3. Deploy the TCA 3.0.0 airgap OVA with a separate FQDN, IP, and certificate.
  4. Configure the newly deployed airgap server to synchronize data from the older version of airgap server.
  5. Shutdown the older version of airgap server.
  6. Configure newly deployed airgap server with backup FQDN, IP, and certificate.
Note: The procedure will cause a downtime of airgap services for about 2 hours. In case of airgap server connectivity issues in TCA clusters during downtime, wait for the services to be back online.
