From one ISPConfig3 server to two servers
My ISPConfig3 server is getting to its limits, so I want to add another server and balance services.
I want to migrate all websites and possibly databases (so websites doesn't have to change its database configuration) to new server, and keep the rest of the services in old server.
I've read in ISPConfig manual how to make a multiserver setup from the start, but I'm not sure if it's possible to simply add a new server and migrate services to it.
My question is, If I add new server to ispconfig, is it possible to sync /var/www between servers, and only change "server" field on website and get it running?
How to make the same for databases? Is it really neccessary to migrate databases to new server?
Thank you for your answers
