[TYPO3-dev] What is the right way to upgrade TYPO3 v4.5x to v7.5.0

[Ghanshyam B. Gohel]

Hello Jigal van Hemert,

Thank you so much for kinda help.

I have checked deprecated log and replace function, path etc.

I have changed everything manually, can we do somethings like PHP constant:

define("t3lib_div","\TYPO3\CMS\Core\Utility\GeneralUtility");
define("t3lib_extMgm","TYPO3\CMS\Extbase\Utility\ExtensionUtility");

This is only rough idea, If we won't use compatibility6 or?, I have seen compatibility6 is in the core with v7.5.0.

Thank you,
Ghanshyam
