The unofficial answer and “opinion only” to your question is yes. You can use one of the terminals as a master as long as it has access to the internet or use a jump drive to copy data files off of the Micros e7 POS system. We have had success with these configurations. You can also use MyMicros.net interface to get e7 data. We cannot speak for any other configuration with experience.
The OFFICIAL and APPROVED answer is that you MUST contact corporate Micros. MAKE SURE YOU CALL CORPORATE MICROS AND VERIFY WITH THEM BEFORE YOU PROCEED!
We assume NO liability for this answer, however we hope this answer will assist you in obtaining the official answer from corporate Micros.
