Upgrade your typo3 in a minimum of time

Typo3 is providing a very nice upgrade documentation. We want to upgrade a Typo3 4.5 LTS (or greater) to Typo3 7.2 LTS within major steps. Basically we need to carry out three steps.

Upgrade from 4.5 (or greater) to 6.2

1. Backup your sourcefiles and Database!
2. We need to deactivate all custom extensions to proceed a clean upgrade.
3. Following further instructions of preparing your Typo3 4.x
4. carry out all upgrade instructions (Ignore typo3_src symlink upgrade!).
5. Download the latest Version of 6.2
6. Archive your current index.php and typo3/
7. Extract index.php and typo3/ from 6.2 archive into your current version.
8. Execute installtool and proceed all steps <your_url>/typo3/sysext/install/Start/Install.php
9. Setup a locale as en_US.UTF8
10. You should now have a clean 6.2 Version.

Upgrade from 6.2 to 7.6

1. Backup your sourcefiles and Database (again)!
2. Download the latest Version of 7.6
3. Archive your current index.php and typo3/
4. Extract index.php, vendor/ and typo3/ folder from 7.6 archive into your current version.
5. Execute installtool and proceed all steps <your_url>/typo3/sysext/install/Start/Install.php
6. You should now have a clean 7.6 Version.
