Mariappan,
Unfortunately, right now it is as written - APM is not supported in Active/Active configuration, so you will not be able to configure both devices in Active/Active mode. What license reasons are you referring to? Active/Active is generally not the best idea when we're talking about a pair of devices due to a greater possibility to overwhelm a second device in case of failover if the capacity is not provisioned properly. It makes more sense in a greater cluster - at least 3 or more devices - but I would advise against Active/Active deployment on a pair of devices unless there is some absolute compelling reason for that(even when it is supported).
