Upgrade Information

This section provides key information about upgrading to this software version.

Supported Upgrade Paths

The following in-service (hitless) upgrade/rollback paths are supported by the OCSLB:

  • S-Cz9.0.0 to S-Cz9.2.0
  • S-Cz9.1.0 to S-Cz9.2.0

Endpoint Capacity Configuration during Upgrade

If you are upgrading from S-Cz8.1.0 or S-Cz8.3.0 to S-Cz9.0.0 or S-Cz9.1.0 as a step prior to upgrading to S-Cz920, ensure that the endpoint capacity configuration in setup entitlements, LB Endpoint Capacity is not greater than 5 million before upgrade. The upgrade may fail if this number is greater than 5 million.

In addition, during upgrade, the number of endpoints in the entitlement should be readjusted if memory is less than 32GB. Specifically:

  • If memory is between 16GB to 32GB, then the total number of endpoints in entitlements should be less than or equal to 2.5 Million endpoints.
  • If memory is less than 16GB, then the total number of endpoints in entitlements should be less than or equal to 1 Million endpoints
