Thank you for your interest in Sitefinity!
There are many approaches, but it all depends on your web site. Here are some of them:
1. You include all web pages as External ones in Sitefinity. This way, all of your web pages will be available in the CMS. You will not be able to edit those pages though.
2. Migrating your design to use Asp.net 2.0 master pages. After you place the content placeholders inside, you are ready to work with the CMS and to add your user controls on the pages.
How you are going to transfer the content depends again on your web site services. If you have RSS service for example, you may think to create an RSS parser, and to use our APIs to store the contents of the rss stream to the appropriate module. Here are some links you might consider for helpful:
We are thinking for some kind of importer tool, but still do not have a clear idea what features it should include.
I hope you find this helpful. Perhaps someone from the community could share his/her thoughts.
