ISPConfig 3 script to move installation from one server to another

ispconfig-migration.sh

#!/bin/bash
# Migrate ISPConfig 3 installation from one server to another
# This script should run on the final/destination ISPConfig 3 server
# You must first install the same ISPConfig on the destination server
# and make sure to create all the users from the previous installation
# (ISPConfig creates users for each client and web page)
# Tested on ISPConfig version 3.0.5.3

I recommend both servers be the same. So update your 3.0 install to 3.1 and make sure everything work before the migration.

Testing the script (3th one) by thoatswold on an IspConfig 3.1 (beta) server. For now there is one thing going wrong and that's about the mysqldump directory at the 'old' server which does not exist yet. So create a directory 'mysql' within your root user directory.

Suggestion :
Use 'ssh-keygen' and 'ssh-copy-id root@ip master server / old ipsconfig server' so you do not have to provide passwords all the time.

Hi, thanks for sharing. I also needed to make a few changes:

• added the letsencrypt folder and settings from the former ispconfig server, otherwise the new server didn't load apache at all due to missing files indicated in the corresponding apache configuration files.
• added a command to create the /root/mysql folder expected in the source server.
• forced to continue the mysql dump even if some minor issue is found in one table for some reason.

I left the modified version from the one shared in comments section in a new github repo, in case, you want to pull changes into your script.

What are the methods of restoring the passwd's and groups?

-=-=-=-=-=-=-=-

Nevermind, assuming it's a simple copy/paste between files?

Getting internal server error 500 on all the sites except the control panel itself. It appears to run and act fine. Anything I missed?

I'm sorry, this script is deleting very important files from my webserver. This is not acceptable. So i think the migration Tool is my last chance :-(
