Hi Alex, We just move from Ubuntu 16.04 to 18.04, koha from 17.05 to 19.11 and went from a 1core 2GB Ram box to a 2 core 4 GB Ram box. What we did was to install everything from scratch in a new Linode and then move the DB from old machine to the new one. Do all tests needed and when satisfied, swap IP between the old linode to the new one. This is a feature from Linode the avoid moving DNS entries when replacing servers. This way give us all the peace of mind required and production site was not touched until the IP swap. About upgrading OS, you might want to check your Yaz & Zebra versions for compatibility and dependencies. About your DB scripts, you might not needed anymore since issue was fixed by mysql/mariadb. You can check versions in koha wiki. We use this guide for moving the DB ( http://kohageek.blogspot.com/2015/08/move-old-koha-database-to-new.html ) In your case, you will need to repeat the mysqldump part for each instance. We will keep old linode for about a month and then delete it. We will pay for two linodes for about 2 months.

Hi Guys,
I’m needing to update my Koha server that hosts 8 separate instances of Koha and just looking for any advice or guidance to reduce disappointment…
Its on a Digital Ocean Droplet, which I’ve taken a SnapShot of and will test the upgrade on a cloned test instance from the snapshot before doing it on production, so its low risk but I want to avoid unforeseen issues that may not show-up for a while.
I’m aware of the notes here: https://wiki.koha-community.org/wiki/Koha_on_ubuntu_-_packages#Upgrade_Instr... but they are quite brief and I kinda expect more issues than “it just works”… Maybe it does - I don’t know yet.
It is currently running:
Ubuntu 16.04.6 LTS Koha 17.11.18.000 MariaDB 10.0.38-MariaDB-0ubuntu0.16.04.1
The only “special” things I’ve done to this server are:
A) install the IndexData repos:
http://ftp.indexdata.dk/ubuntu xenial InRelease http://ftp.indexdata.dk/ubuntu xenial Release
to upgrade Yaz and Zebra as there were issue with my Koha instances handling some Asian languages (Thai I believe) that were improved with the later versions.
B) Add the Startup scripts to each MySQL DB to reset the sequence numbers etc on boot.
Questions in my mind:
1) Do I just alter the APT Koha repo to say 19.11 and run update/upgrade in one step or is there a need to step through each major version to get there?
1) Should I also upgrade Ubuntu to 18.04 LTS or just leave it on 16.04 LTS? This might affect the Yaz and Zebra versions as well.
Any comments or advice?
Regards
Alex Shepherd
