[TYPO3-english] Re: Error upgrading from 6.2 to 7.6

[Marcel Rosenberger]

The error means that you have values in the columns "image" and "media" which are incompatible with the new column definition.

You can execute the following directly to the database before running the update wizard again:

UPDATE pages SET media = '0' WHERE media IS NULL; 
UPDATE tt_content SET image = '0' WHERE image IS NULL; 
UPDATE tt_content SET media = '0' WHERE media IS NULL; 

This solved the error for me.
