Hours are hours and they should count but I'm not sure about the specific training requirements which will differ to one degree or another. Believe me if they could philosophically justify a concept such as EASA hours, CASA hours, FAA or anywhere else hours, they would do it but it doesn't really make any sense. I'd imagine you'd have to unlearn some procedural things and relearn them the way they want you to do it but that should be straightforward enough. What paco said about your logbook I'd agree with. Good idea also to scan them and keep a backup copy on a USB drive.
Good luck.
