[Evolution] How do I migrate to Evolution from Thunderbird?

[Jai <i922sparkcir gmail com>]

Hi, this is my first time using this mailing list.

I am an Ubuntu 7.04 (herd 5) user and I want to completely switch to 
evolution, but I have thousands of emails archived within Thunderbird 
and over three-hundreds cotacts. I need to be able to search within old 
email, and use the same contacts.

Thank you guys for your help.
