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 ?</P><P>Should IMC upgrade the switches with ISSU one after one in order to garantee the high availability ?</P><P>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.</P><P>I dind't find information on the guide</P><P>Thanks</P><P>David</P> Wed, 23 Aug 2017 09:36:36 GMT Daddy72 2017-08-23T09:36:36Z https://community.hpe.com/t5/imc/imc-deploy-device-software-issu/m-p/6974635#M4007 <P>Hello,</P><P>I'm trying to use Deploy Software on device using ISSU feature on IMC.</P><P>The goal is to upgrade a stack of 4 units.</P><P>I did the deployment and the entire stack was succesfully upgraded by IMC unsing ISSU.</P><P>However, IMC reboot 2 switches of four (in my case) in the same time.
