TYPO3 upgrade
From old to current.
In one project.
We bring your TYPO3 site up to the current LTS version, even if there are four major versions in between.

Version status · October 2026
Which version does your site run on?
Older TYPO3 versions only get security updates through the paid ELTS programme. Every version without support is an open window.
| Version | Status | What we recommend |
|---|---|---|
| TYPO3 14 | Current, LTS | Target for new projects |
| TYPO3 13 | LTS, with security updates | Keep it up to date, plan the move to 14 |
| TYPO3 12 | ELTS only | Upgrade in the coming months |
| TYPO3 11 and older | ELTS only or no support at all | Upgrade now, usually across several versions |
In most cases we can tell your version from the outside. Send us the address and we will tell you where you stand, free of charge.
Upgrade in four steps
Compare first, then switch.
Your live site stays online until the new version demonstrably shows the same.
Review what is there
Version, extensions, custom theme, PHP and server. You get a written assessment of effort and risks.
Migrate on the side
We lift a copy version by version. Every step is committed separately to version control and can be traced.
Compare page by page
Every page of the old and the new version is compared automatically for text and layout. You see any differences before go-live.
Switch over
One date, one switch, one report. Afterwards we keep the version current if you want us to.
What it includes
Not just the core.
An upgrade is finished when the whole site runs again, not when the version number is right.
Core and database
Every intermediate step with the official upgrade wizards, database changes included.
Extensions
Update, replace or cleanly remove whatever no longer exists for the new version.
Custom theme
Templates, TypoScript and content elements adjusted so the site looks the way it did before.
PHP and server
Moved to a supported PHP version, and to our hosting if you like.
Forms and redirects
Contact forms, enquiries and old addresses keep working after the upgrade.
Report
What we found, changed and removed, in writing and easy to follow.
Upgrade check
Know first, then decide.

FAQ
What clients ask before an upgrade.
Will my site be offline during the upgrade?
No. We work on a copy. Your site stays online until the new version has been checked, then we switch over on an agreed date.
Do I pay for every version separately?
No. We go through all the necessary intermediate steps in one project and charge for the project, not for each version.
What is ELTS?
Extended Long Term Support: paid security updates for TYPO3 versions after the regular end of support. ELTS can be a bridge, but it does not replace the upgrade.
Will my content and URLs be kept?
Yes. We compare every page of the old version with the new one and check that known addresses keep working or redirect cleanly.
Another agency built our site. Can you still help?
Yes. Many of the sites we upgrade were originally built by another agency, PUREA for example.

Where does your site stand?
Send us the address and we will tell you, free of charge, which version it runs on and what an upgrade would involve.
