Plan your TYPO3 upgrade in four phases
From inventory to go-live, with every extension on one sheet. Written by our team, with real TYPO3 v14 backend screens.
- Know which extensions block v14 before the project starts
- A fixed upgrade order that avoids the usual errors
- Real backend screens: Upgrade Wizard, Extension Scanner, compatibility report
Free support ended years ago. Expect a project rather than an update: Composer, templates and extensions all move. Start with phase 1.
Free support has ended. Plan time for template and extension rework, one LTS at a time.
Free security fixes ended in October 2024. Go via v12 and v13, and run the wizards after every step.
Free security fixes ended on 30 April 2026. Via v13 to v14; check every extension first.
Free security fixes until December 2027. A good moment to prepare v14 without time pressure.

Fifteen pages you will actually use
A word up front
Why upgrades stall, from Jürgen, and the team behind the playbook.
Where do you stand?
The whole process on one page, support dates of v11 to v14 and the safe path to v14.
Phase 1: Take stock
Worksheet, deprecation log, Extension Scanner, and the compatibility report in the backend.
Phase 2: Staging and backup
A copy, a tested restore and a written way back.
Phase 3: Upgrade and migrate
The order that avoids errors, upgrade wizards in the v14 backend, risks by severity.
Go live, secure it, size it
Test list, 10 security points and the seven factors that make an upgrade bigger.
From TYPO3 v11 to v14: the Upgrade module you will work in
Drag the handle. Same tools, same order, a calmer backend. The playbook shows each screen with numbered steps.
TYPO3 v11TYPO3 v14Five steps, one at a time
Take stock
Version, PHP, every extension and your own code on one sheet.
- Fill in the worksheet
- Check each extension against v14 on TER
- Run the Extension Scanner on your own code
Staging and backup
Whatever can go wrong goes wrong on a copy.
- Set up a staging copy
- Back up and test the restore
- Check PHP 8.2+ and the database version
Upgrade and migrate
Core, extensions and database in a fixed order.
- Raise PHP, then update with Composer
- Run the upgrade wizards
- Analyze the database structure
Test and go live
Test what visitors and editors use every day.
- Backend, frontend, forms, scheduler
- Editors sign off on staging
- Deploy, flush caches, spot-check
Secure it
A fresh upgrade is the best moment to tighten security.
- Two-factor login for admins
- Lock the Install Tool
- Read the Status Report
Every extension on one sheet
One row per extension: source, version, ready for the target or not, and what you do with it. Dropdowns keep it fast, colours show the open work, and the summary counts itself.
- Five tabs: start here, site, extensions, go-live, summary
- Opens in Excel, LibreOffice and Google Sheets
- The same list we need for a quote, if you want help later
Screenshot in, compatibility list out
Our AI skill for Cursor reads a screenshot of your Extension Manager, asks TER about every extension and writes a CSV with columns for v12, v13 and v14.
