Mailserver Migration To ISPConfig Server
I have 6 servers on 2 datacentres, ie. 3 servers on each datacentre. To simply things, lets call the datacentres as A, which is the main datacentre and B, which is like the failover datacentre.
I have one server running on ISPConfig on DC A for almost 3 months now and everything seems to be working fine. That server is running the web and MySQL server while all emails are directed to an external server on DC B, which is running on Postfix.
Is there a way for me to install ISPConfig on a fresh server on DC A and then migrate all users and emails from the old server to this new server? Preferably this could be done without re-creating all the users all over again. Is there a way to do this?
Another issue that I am having is to create another webserver on DC B and somehow mirror the files on the main webserver in DC A to this new webserver. What is best way to do this.
Thanks and hopefully, someone could help me with these 2 issues.
