We are potentially facing the same dilemma. We are currently using a fixed license on our VM which runs our daily CI/CD tests without any issues. I am in the process of evaluating an upgrade to a current release, but do not want to jeopardize losing the benefit of those tests running daily if we must / be required to have a floating license for a VM.
ihorstep - Unfortunately, we have been put on hold till our IT department can determine the "best" user ID we should use for that VM instance (the associated email will need to be public facing to receive the link to create the SB License server account). Once IT lets us know, we will update our CI/CD plans to use the associated "accessKey" information and let you know if all is fine.
