Customer of ours has just requested an MX with Advanced Security and some additional MR's. When i went to order the MR's i found that there are Enterprise and Advanced Security licenses for the MR's which i wasn't aware of. I know you can't mix the two licenses when it comes to MX's but can you when it comes to MX and MR's together?
Furthermore, whats the difference with the two licenses when it comes to the MR's? Searching online i didn't find anything too helpful.
