Anyone knows the steps to reimage an ISE VM node.
Current disk size is not enough and we would like to increase VM disk size, but Cisco doc says ISE node reimage is required for new VM size to be reflected.
Current is primary node. There are two ISE nodes, in HA. One in DC and other DR.

It is VM - there is no process for re-image ( rather we call re-install)
Personally - i would build 2 new VM with correct Disk requirement and future requirement - and migrate them
look at the requirement :
I used below document on standalone mode to increase VM disk space it works as expected in the LAB environment, not sure side effects in the Live :

Most of the time used as generic term, but purpose is same.

I would reimage these one at a time from the ISO. Download the correct ISO for your version from Cisco.com, shut down the nodes one at a time, mount the iso to the vm and boot from it. Select option 1 for keyboard and mouse install.
When finished installing, you will have to apply the same top patch following reimage, and install the correct trusted certificates and node certificates as before. You can back these up from the gui prior to reimaging.
But as you found documented, the only way to increase the disk space is to install the OS again.

Once you shut down the VM, increase the disk size. Then you can reinstall using the larger disk.
