How to … update TYPO3 4.2 at fragmente

How to

After the release from TYPO3 4.2.8 i decided to post a small, usefull description to update/upgrade the core files from TYPO3.

You won’t need more then 10 minutes! Just follow these steps (more details, see here):

Download TYPO3 source
Backup your Database and the following folders:
- t3lib
- typo3
- fileadmin
- uploads
Upload the source files to your webserver
Start the Upgrade-Wizard (Install-Tool)
Compare & Update your Database online
- select Database Analyser
- click COMPARE at “update required tables” and do the proposed updates until the Install Tool says, that everything is OK.
Install/Update static tables and description tables (only if needed)
- use the InstallTool
- select DataBase Analyser
- click IMPORT at “Dump static data”
- “import” the whole file
- click “write to database”
Clear cache tables
Clear configuration cache
or just delete “temp_CACHED_ ” files in /typo3conf/ directory
check for Extension-Updates (Backend -> Extensions -> Update)

THATS ALL! after a short test – your webproject ist fresh and up to date!
