How to fix Jupgrade Migrating undefined error when upgrading to Joomla 2.5

by filed under Joomla.
Recently I had an error message while migrating and old Joomla! 1.5 site to the new Joomla! 2.5, jupgrade failed with “Migrating undefined” error. After digging in the code I found a solution: You have to edit two files: jupgrade/installation/models/configuration.php jupgrade/installation/models/database.php and insert the following line near the top of the script: require_once JPATH_ROOT.'/jupgrade/libraries/cms/model/legacy.php'; When done (after the failed upgrade), you can retry the migration checking the following options in Jupgrade configuration:

    In some cases JPATH_ROOT don`t work. Change the line for : require_once JPATH_INSTALLATION.’../libraries/cms/model/legacy.php’;

    Many, many thanks.

    Who knows why these two lines are missing in the original JUpgrade script.

    YEAHHH!!!
    Für die die es nicht schaffen:
    1. Im root-Verzeichnis der 1.5 Installation einen Ordner jupgrade anlegen
    2. die neueste 2.5.x in dieses Verzeichnis entpacken.
    3. in diesem Verzeichnis den oberen Pfad folgen und die beiden Dateien modifizieren, am besten gleich unter: require_once JPATH_INSTALLATION.’/helpers/database.php’;
    das hier schreiben:
    require_once JPATH_ROOT.’/jupgrade/libraries/cms/model/legacy.php’;
    4.Einstellungen wie im Bild oben vornehmen und ab gehts…

    I have a requirement to build one parent site and few child sites..using domain and sub-domain concept and want to have installations of joomla at parent and all sub-domains. But I want only my parent site to hold user data and Alpha user points data while my child sites would be hosting components and modules separately and use user data and Alpha user points data from parent site.

    Could any one suggest me is it a good Architecture to go and is there any extension or component already available to achieve it. Example
    below:

    parent site movies.com Child sites braveheart.movies.com, troy.movies.com

    I will have forums, blogs and other component installations at braveheart and troy sub-domains seperately while my Alpha user points and users db/tables would reside at movies.com(main domain).

    It’s like single-sign on or Centralised Alhpa user points, but free to install same component and modules at different sub-domains.

    Highly appreciate any replies or solutions proposed

    There is no “Parameters” icon… Do you know what can be wrong?
