[Koha] How to Update and Upgrade Koha

Hi, as with anything else, you should first have a good (tested) backup 
of everything.  Koha, server software, and database.

Then, if you used the debian packages, you should check which version 
you are "tracking", something like:

grep -Ri koha /etc/apt/*

would return something like:

http://debian.koha-community.org/koha 19.11 main

That means there is a file /etc/apt/sources.list.d/koha.list which you 
should edit and change to the version you want to track now.  The 
content of the file would be:

deb http://debian.koha-community.org/koha 21.05 main

if you want to track koha 21.05

Then you would:

apt-get update
apt-get upgrade

and it should do the upgrade.  With the following exception, if apt-get 
upgrade says it would need to update mariadb-server or mysql-server, 
then you should upgrade that first and separately, like this:

apt-get update
apt-get install mariadb-server-10.3
apt-get upgrade

If you don't upgrade mariadb first, it will be DOWN when koha wants to 
upgrade the database, leaving you with a half upgraded system.  (And 
using that backup).

Hope this helps.
