Yesterday, I encountered a new issue for a customer. They received an error message stated that the trail key was to expire in a few days. “WTF!!!” was my first thought, but it seems this is a common scenario according to this post.
You will recieve a similar error message:
The most important thing to remember. Do not let the trail key expire. If you do so, you will have to re-install the complete server and import the organization one more time. This will cost about one workday alone.
The Product key can be changes from the “CRM deployment Manager”.
