- Comment/Story/Migration tips:

Before use iRedMail and iRedAdmin-Pro, my company had an old server with postfix and a python script to manage postfix.  The only features of this system were mailboxes and alias and of couse the server wasn't secure enough. Now with iRedMail and iRedAdmin-Pro we have all same features with a lot of extras and more secure than old server.
I've to say that forum responses are fast and help to fix the problem.

Migration tips:
- Create all domains in new server, then create an user and an alias to investigate the sql structure.
- Extract the old server user and alias list and create an script to generate sql transactions with that list.
- In my case i had to migrate old postfix server with "domain/user" structure to new "domain/u/s/e/user-2014.01.01.00.00.00" structure. This can be done with a bash script whith ls, cut, find, and rsync or mv.
