The Import button is greyed out in the latest version of the Zoo on our new Windows 2008 server
Yes, this is true. We had some issues with the import feature due to the license validation that is required for Rhino 5 keys. Hopefully we can roll out an update that fixes this in the near future.
What is the easiest way then to get my licenses easy from the old license server to the new license server?
Wait... or is there another method?
Just delete your license(s) from the old server and then add them to the new server.
