Hi Constantino, I would recommend setting up a separate test installation with the Koha version you want to upgrade to and then move your database there. Posts like this one might give you some good hints: http://kohageek.blogspot.com/2015/08/move-old-koha-database-to-new.html Hope this helps, Katrin On 07.03.25 18:30, Costantino, Fernán wrote:

Hi ppl, how are you.

¿Is there a guide over there to solve this upgrade? The machine has Ubuntu 12.04. I want to migrate to a new server and new stable Koha.

Thanks.
