[Koha] Upgrade: Ubuntu 16.04.6 LTS / Koha 17.11.18.000

[Alvaro Cornejo]

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.

Regards

Alvaro
