I am trying to upgrade an existing project based on the "magnolia-enterprise-bundle-parent" (Magnolia 5.3) to Magnoli 5.4 (using STK). I have done what is written on this page:
https://documentation.magnolia-cms.com/display/DOCS/_how+to+update+to+5.4+from+5.3.x+or+5.2.x

but this doesn't work. If I startup Magnolia, then it "crashes" and I see in the log that the dependency manager is logging quite a lot of message, such as:

Module Magnolia Language files : French (version 1.0.6) is dependent on standard-templating-kit (version 2.9.1/* - optional), but Magnolia Standard Templating Kit Module (version 2.9.0) is currently installed.

Module Magnolia Module Forum (version 3.5.0) is dependent on public-user-registration (version 2.5/* - optional), but Magnolia Public User Registration Module (version 2.4.3) is currently installed.

You can see here that Magnolia is using the version which are listened on the Magnolia upgrade site (see link above). But Magnolia itself is expecting a newer version. How should this work???

Have now seen, that there is a bundle available "magnolia-enterprise-pro-stk-bundle" which is including the STK. Have tried to download it, but it asks me for a login:
https://nexus.magnolia-cms.com/content/repositories/magnolia.enterprise.releases/info/magnolia/eebundle/magnolia-enterprise-pro-stk-bundle/5.4.9/magnolia-enterprise-pro-stk-bundle-5.4.9-tomcat-bundle.zip

From where can I get the login credentials? Our company (Netcetera / Zürich) is partner of Magnolia. Therefore I assume that I am allowed to access this enterprise version.
