SEO URLs

Hi all

I have migrated a users system from Zencart to Opencart. They have spent a significant time and effort/cost getting a good rank within the search engines, in particular Google, and the SEO urls currently are as folllows

http://www.domainname.co.uk/bp5bubblepo ... 0c0863daa4

Now obviousley I need to be carefull in the new site to ensure these urls stay the same or they end up starting from scratch with their rankings.

I can add bp5bubblepouchbag280mmx375mm150s-p-65 as the SEO keyword, and other than the Zend the url is identical on the current and new site, however I wanted to know this.

Does anyone know if the Zend aspect is included in the url google uses?
Also, in opencart viewing the same page the .html is not visible, but in the zencart site it is visible, will this cause any issues at all

URLs need to be exact( else you need to state permanently moved ).

all done, was fairly easy using google Adwords editor and the excel export facility took only a few days (few hours a day) to get everything all back to working.
