Hello MdGanji, If you are using the trial license then at the end of the trial period options will be removed.  If you had a license and it is going to expire soon, then a VSA with an expired license will continue to work but won’t allow you to make changes. Please let us know if you have any other questions.
Hi, As I happened to recommend the UnityVSA virtual appliance to a friend in order to download and give it a test, noticed that it should not be used for more than 45 days. Does the license expire immediately after 45 days or it's just a legal and EULA warning and binding? We are not going to use it more than the 45 days period in a production environment but anyway it's spooky to set up a bunch of servers and configurations and loose them out of the blue atthe end of 45th day. There may be some remaining tests at that time before we finish it up. Regards, Mhdganji
