Changes of some internal URLs

[Marfola]

Two months ago we changed the URL of some internal pages of our website and Google indexed them very quickly (2 or 3 URLs by day). In a couple of weeks all the modified URLs were re-indexed.
We did the same things two weeks ago for another section of our website, but Google doesn't seem to react. Google is archiving and deleting the old URLs, but no new URL has been indexed till now! (MSN is updating our website correclty).

Which is the difference? Why the same modification got two different behaviour? Is it normal that in a couple of weeks no new URL has been indexed?

All you can really do is double check all the links on your site making sure non are pointing to the old url's and use a 301 redirect..

What have you done differently this time ?

You may just need to wait it out..
