HA vCMP with different resources

I haven't never tried this configuration, but I guess that if both vCMP's has same modules deplyoed and the same release the HA should work fine. In my experience, the HA feature is related to modules/release.

Guests in a device group that differ from one another in terms of core allocation and slot assignments are considered to be heterogeneous guests. In this case, load-aware failover is an appropriate failover method because the guest administrator can define a relative capacity and relative traffic load for each guest.

Within a Sync-Failover device group, a guest can only mirror its connections to one other guest. The two guests, as mirrored peers, must each reside on a separate chassis with the same number of slots assigned, on the same slot numbers, and with the same number of cores per slot.
