It's important to keep in mind that this is an upgrade path you
carefully have to do. Check each new version for the requirements
regarding PHP and MySQL versions. You will have to upgrade those too
during the whole process when a new TYPO3 version doesn't support the
PHP and MySQL version you have at that point.

Database Compare and read the INSTALL.txt, NEWS.txt and the upgrade
guides in the wiki  for thing that need extra attention.
