Cause

The SGOS 7.2.3.5 and earlier has issue if run the migrate upgrade scenarios.

If the appliance was never upgraded to 7.2.x or 7.3.x previously, upgrading to this release will preserve the previous ciphers selection and enable TLS 1.3 by default. 

To apply the fix if the appliance was previously upgraded to 7.2.x or 7.3.x, you must remove the existing SGOS 7.x configuration before upgrading. 

Issue the #remove-sgos7-config command, restart the appliance, and then install this release.
