IMC Deploy device software ISSU

[Daddy72]

Hello,

I'm trying to use Deploy Software on device using ISSU feature on IMC.

The goal is to upgrade a stack of 4 units.

I did the deployment and the entire stack was succesfully upgraded by IMC unsing ISSU.

However, IMC reboot 2 switches of four (in my case) in the same time. So, the upgarde is done in the 2 first switches and then in the 2 last switches. How can we control the order IMC do the upgarde ?

Should IMC upgrade the switches with ISSU one after one in order to garantee the high availability ?

For example, I have a stack of 4 units, in my core switch and the link-aggregation to the access switches are made on the unit 3 and unit 4. I want to control the upgrade process to be sure the unit 3 and unit are not rebooted at the same time. In the lab I prepared to test this functionnality, the uni3 and unit4 were rebooted at the same time.

I dind't find information on the guide

Thanks

David
