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.
@till, do you know if migration from mysql Ver 15.1 Distrib 10.0.34-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2 (on Ubuntu 16) to mysql Ver 15.1 Distrib 10.1.26-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2 (on Debian 9) is going to cause a problem? It's a downgrade in version, but only for a tiny bunch of changelog entries...
To me, it looks like an upgrade: from MariaDB 10.0.34 to 10.1.26. Debian 9 is much newer than Ubuntu 16.04, so it should be an upgrade and not downgrade.
Thanks, my tired eyes didn't see the .1. in the middle ;-) I migrated all under /var/lib/mysql 1:1, and ran # mysql_upgrade -u root -p and it looks like it's 100% OK.
