I have two sets instances under CAL on AWS to support my openSAP courses. I would like to have these instances linked to a different AWS account. As these are largely "canned" instances with most of the content provided the simplest way seems to be to recreate them. Looking at the CAL UI, I can't activate them twice and I can't change the linked AWS account while I have existing instances. If I terminate the instances, will I be able to change the linked account and then recreate the instances again?
