Hi all,

For testing updates of Zimbra I make a disaster recovery from the production Zimbra server inside a virtual machine. After this, I have a copy of the production Zimbra system with all accounts (>700), but only one or two accounts has real data from a backup.

With Zimbra 7.x you have to activate your license. I have read the Thread http://www.zimbra.com/forums/adminis...b-license.html, and I try to use a trial license for the testing machine. The installation went fine with the trial license, but inside the admin interface the real license is still in use. I try to update the license via the admin interface but get the following error

can't change install type from regular to trial
How can I use the trial license with my testing machine?
