    Hello everyone,

    I've got several ISPConfig installations (versions 3.0.x) on Debian 8. These I want to update to Debian 9 and ISPConfig 3.1.x.

    All these instances are virtual machines on one host. Because I have to migrate them to another host I have to change the IP-addresses and hostnames of the virtual machines, too.

    What is the proposed procedure to accomplish this? In which order should I do the updates and in which places do I have to update the IP and hostname?

    Thanks for your support!

    I would proceed like this:
    Move a copy of the virtual machine to the new servers, there you:
    1) Change the IP address in /etc/network/interfaces file, so that you can connect to the internet again.
    2) Update Debian to 9.
    3) Update ispconfig and choose to reconfigure services.
    4) Run Tools > resync in ISPConfig on the websites to rewrite the server config.
    If you used the IP address instead of * in the website settings, then you might have to adjust the IP in ISPConfig. Same with DNS records.

    Edit: It worked out well! Thanks again for the procedure. :)
