Changed the main domain

[Eagle Eyes]

I have changed my main domain http://www.pakistaniforces.com/ to http://www.defence.pk/ and i also change the site name from Pakistani Forces to Pakistan Defence. However, in the search engines all i see is that pakistaniforces.com domain name is still being used. How long will it take the google to replace it with defence.pk without dropping my PR, pages indexed etc.. Do i need to do anything?

make sure you have a 301 redirect from your old domain. It could take several months... I'm going through the same thing right now.

Can you tell me what kind of redirect you got in .htaccess? Let me know please. Thanks. :)

It takes a long time to replace and the pagerank algorithm maintains your pr and it shall not let the pr effected.
