PT12 subscription - access to earlier versions?

I come from the world of Media Composer where we rent v8 (the latest) but have access to all versions back to v5



Does the same hold true if I rent PT12? Will I be able to access a version that works on the old 17" MacBookPro Intel Core Duo (i.e. not i5 which is minimum for PT12)?



What version would that be?



I own an old (v7) ProToolsLE - but am guessing that does not work for upgrade purposes?



Thanks
