[TYPO3-english] TYPO3 4.3 upgrade

[Bas Heutink]

Hey all,

2 questions.

1. A client of mine has an installation with TYPO3 4.3.2 (Yes they stil 
exist :( ) Can I upgrade this installation to TYPO3 4.7.3 (latest stable 
release) at once? Or should I do it in steps, i.e. upgrade to 4.5 first, 
then to 4.6, etc... Are there any problems I could encounter when 
upgrading such an old installation?

2. Is TYPO3 4.3.2 compatible with PHP 5.3?
