Typical migration duration

"The migration to TYPO3 v12 LTS went smoothly. Our load times more than halved, and the editorial team finds the new backend significantly easier to work with."

Frequently Asked Questions About TYPO3 Development

Which TYPO3 version do you migrate to?

We migrate to TYPO3 v12 or v13 LTS, depending on your requirements. Both versions offer long-term support and are officially maintained by the TYPO3 Association.

Can you take over and maintain existing extensions?

Yes. We analyze existing custom extensions, check their compatibility with current TYPO3 versions, and take over maintenance, updates, and further development.

Do you also offer TYPO3 training for in-house editors?

Yes. We offer hands-on training for editors and administrators so your team can operate the backend independently and confidently.
