[TASK]  Fixes to use smoothmigration with both LTS Versions

Hi, this version is compatible with TYPO3 6.2 and 4.5
Hi, so you can check and migrate extensions (which are not compatible with 6.2) on new TYPO3 6.2 and not need an TYPO3 4.x installation . 

The Workflow can be:
Do core update to 6.2
Uninstall all Extensions
Check and migrate with this great extension ;)
install all extensions
