Hi: What are the necessary files to backup and restore if one needs to migrate from the server with ISPConfig3 with Apache2 to another new server freshly installed with ISPConfig3 (nginx)? The old server is running Debian Squeeze and the new one Debian Wheezy. Thanks! PS: Sorry posted to a wrong forum thread. Could not find how to delete this post? @moderator: Can you please move this to the ISPConfig3 section of the forum? Thanks!
