Actually I'll look at SEO-friendly URL's as an advantage here. Whether you
have to rewrite 1 rule to automagically use the new url pattern or half a
million it's all about making it easy for your users/customers. You don't
want to make it difficult for them because /you/ changed software. If they
go directly to you buy-now page, you want to get there directly and not
present a search page saying, 'we changed software, please search for the
buy-now page, which has been relocated due to change in software (and we
couldn't bother to send you there automatically as it costs us to much and
you will your spend money with us anyway)'.

That is, of course:
- if you're selling products/services which are also easily bought
somewhere else. It's all about the cost/advantage ratio.
- if you linked from elsewhere. If everybody enters your site using the
home-page, it's not a problem either.
