When a rollback operation is performed, the NSX Advanced Load Balancer Controller or SEs will transition to the previous major version of the software. Selective rollback is possible for the Controller and SE groups.
The following rollback options are available:
System: NSX Advanced Load Balancer Controller and all SE groups. This option is disruptive.
Controller: NSX Advanced Load Balancer Controller only. This option is non-disruptive.
SE-group: all or some of the SE groups. This option is non-disruptive.
Note:
Rollback of the SE Group will be to the previous version.
