SEO URLS in OC 2.0

I'm thinking about upgrading to 2.0 from 1.5.6.1 where I'm using UKSB's automatic SEO URL extension. I see in 2.0 there is a SEO URL field under the data tab, but in the demo it doesn't seem to work (still displayed the long URL paths). Just confirming this feature will provide true SEO URLs (i.e. /keyword-keyword1-keyword2)? And, does it do so automatically or do I need to input them myself? Reason I ask is UKSB doesn't have a v2.0 extension and I don't want all my URLs (which are linked to on lots of sites) to fail to link

Thanks,
Garret

URL alias in Oc 2 is work like on 1.5.x, you need to add them manually.

It's not work in demo because most possibly they not activate it
