Change from Manager Cloud to Server Version

I have been using Manager Cloud version for the last two years but now I have infrastructure to host manage how do I change to the server version

Sounds as if you do not have enough technical knowhow to run your own server if you are asking this question

Backup all business and import these into the Server Edition you setup.

Please note that Manager Cloud is cheaper than Server Edition (see discussion and costs at Installing Manager Server edition - #29 by Tut and at Installing Manager Server edition - #24 by Lance) and does not ras @Joe91 points out require skills or knowledge regarding server setup and maintenance.
