Updating vThunder in HA Pair - how to handle avcs with vrrp-a

Hello, I am looking at upgrading our vThunder load balancer and am wondering how I would go about disabling the avcs and vrrp-a to perform a successful upgrade of the secondary device.
As I understand it, when just using vrrp-a, I could simply upgrade the secondary device, and then force the 1st device to standby with "vrrp-a force-self-standby" and promote the secondary unit to master.
However, I am also using avcs, and I understand this makes the process a bit more complex. Does anyone have any tips on doing this process when using avcs and vrrp-a?

vcs vmaster-take-over 255 on the secondary unit after upgrading it.
The vcs process wil detect the primary(now secondairy) unit with a lower version and will upgrade && reboot it automatically.
I suggest you lower the priority instead of doing a vrrp-a force-self-standby to prevent it becomming active again after reboot.
