My Sites database restored but still creates new site collection for already existed user

Hi,

I have two MOSS 2007 server. Migrating content from one to other. I migrated My sites database from server 1 to server 2. From Server 2, when click on Mysite from the top link of my site then it is creating new site collection instead of picking the already existed/already created site for him. Any idea? how to resolve this issue.

Thanks,
