[Koha] How to return from version 17.05 to 16.05

[Katrin]

Please note, that you will need to use your backup from before updating 
to 17.05, because you can't undo the changes to the database structure 
easily.

 From reading one of your earlier emails - is it possible that you are 
using MySQL 5.7  instead of MariaDB?

The problem with returning items will probably remain, as we have 
implemented a block on returning items when the issue_id already exists 
in old_issues in 17.05, 16.11, and 16.05. Please see here:

You need to fix your data in order to get around this and implement the 
init script.

Hope this helps,

Katrin
