How can I revoke an issued Per Device license to make it available for a new client?
You can’t really do this, and it shouldn’t be necessary either. TS CALs have an expiration date of 52-89 days after issueing. Licenses that are not used (because the client does not connect to the TS anymore) will automatically be returned to the LS after the expiration date. In the meantime, your new clients will get a temporary TS CAL, which is valid for 90 days. Note that these time periods are choosen to make sure that your temporary license lasts long enough for the old license to become available again. So replacing one client with another can never cause you to run out of TS CALs. If you are reaching the end of the 90 day temporary license period without having TS CALs available, it means that you have been connecting with more clients than you have licenses and you have to buy extra TS CALs. That said, there is a way to get rid of your license history, and that’s by wiping the license database and installing your licenses from scratch. This requires that you have the paperwork
