CARP and VLAN and LAGG question

[loganx1121]

I'm planning to get a second firewall of the same hardware and doing HA but I'm a little confused about where the VIPs need to be.

There will be a single cisco switch running 2, 4 port LAGs to both firewalls.  All of the VLANs will pass over these LAGs.  The ISP connection will go to a switch and then from the switch to the firewall.

Standard HA setup seems pretty simple, but I'm wondering how I would do HA on the backend of the firewall with the LAGs and VLANs.  Would each VLAN need a VIP configured for it?  Or would that mess things up because the VLANs are running over LAGs?  If each VLAN does need a VIP should that be configured as a CARP VIP?

Thanks in advance.
