By the end of this year I will be migrating my company's SmarterMail server to a 2012 server. The longest part of this process will be uploading user data.
I would like to upload this data per domain, which means that I'll need to run two instances of SmarterMail in tandem.
I remember this being an option a few years ago but am unable to find any posts related to running two servers with the same license for a small period of time. Is this still possible?
