==================

Hi,
I am in the process of upgrading from an ancient 3.28.5+220405 version to the latest release. It is working quite well up until 6.15.3:
I am able to do arbitrary intermediate upgrades or just jump straight to 6.15.3.
But I cannot upgrade to 6.15.4 or 6.15.5. This is the error message that I get:

CDbExceptionCDbCommand konnte das SQL-Statement nicht ausführen: SQLSTATE[42703]: Undefined column: 7 FEHLER: Spalte »token« existiert nicht
LINE 1: ...5282,993188,985571,992965,994275,994942,996579,998638,token)
^. The SQL statement executed was: UPDATE "surveys" SET "access_mode"=:access_mode WHERE sid in (112745,123624,[...],998638,token,

"column 'token' does not exist"

Does anyone have an idea how to resolve this problem an upgrade to the latest release?

Thanks in advance!

edit: Sorry, I confused the version number. It is all about 6.15.x, not 6.14.x
