Migration¶

An automatic TCA migration is performed on the fly, migrating all occurrences to the new TCA type and adding a deprecation message to the deprecation log where code adaption has to take place. Occurrences are all columns, defined as $TCA['ctrl']['languageField'], as well as all columns, using the special=languages option in combination with type=select.

Note

The migration resets the whole config array to use the new TCA type. Custom setting such as field wizards are not evaluated until the TCA configuration is adapted.
