- For an ISE VM you only need to shutdown the (a) node, change the memory in the hypervisor (settings for the VM); and
boot it up again; afterwards issue the command show application status ise
(check if everything is normal)

@Mark Elsen before I proceed with memory upgrade of primary admin node I have to promote secondary admin to primary is my understanding correct ? Secondly once I shutdown the primary admin once the secondary admin takes primary role does it will cause any outage ?

- @M Talha - It will not cause any outage ; also since that operation doesn't take much time , there is no need to promote the secondary admin to primary ,
