Support System Administrator

When updating to version 7.6 I get the following error:

$ trytond-admin -c /etc/tryton/trytond.conf -d tryton --all

Traceback (most recent call last):

I have no idea which model I should delete or which database table.

Have you checked the migration guide Migration — Tryton Documentation? You have to make some changes to the database before you can upgrade.

Thanks, I didn’t know there wasn’t that documentation.

5

Yeah, it used to be here on the forum in a special category, but it silently got moved to the new location. Hopefully this will help others as well.

It was not silently, it is clearly in the announcement, the former link redirect to the new place and it was done publicly on Add manual migration to documentation (!1993) · Merge requests · Tryton / Tryton · GitLab.

Well, I can’t find anything here on the forum where most of the people look. Also the link in the news of the release is pointing to How to setup a database — Tryton server instead of Migration — Tryton Documentation.

Can do nothing if people does not look at the right place.
We are not going to duplicate all the discussion about the development in the forum for those who look only to the forum.

it is pointing to how to upgrade to a new series which has a warning pointing to the migration :person_facepalming: .
