Increasing CPU on VM Security Gateway

[Tu2pel]

We have a VM gateway that is still running R80.10 that I need to upgrade to R81.10. The VM has only 2 CPU core and 4GB memory and we are looking to upgrade the CPU and Memory. My query is, is there any SK or steps that needs to be done for the Checkpoint OS to recognise the additional VM resources ? (e.g. when additional disk is added, it has to be extended as a physical disk for the CHeckpoint OS to be able to use it, so something similar)
