Using the following Blogger.com template, I have been able to redirect all the traffic hitting my old Blogger.com generated pages to the new pages hosted under DasBlog. If you want to try this, change the dasblog_root variables, paste into your Blogger.com template, and then republish your blog. It’s probably a good idea to backup your old template first. No warranties or guarantees, use at your own risk!

One Man Shouting 
Some browsers don’t have javascript, or some people turn it off. You could do something simpler like this:
html
body
META HTTP-EQUIV="Refresh"
CONTENT="6; URL=http://your.new_url.com"
/body
/html
ChAnge to "CONTENT="6;
To your desired refresh interval
(I took out all the Opening & Closing <> tags so the comment would post! 🙂
The META redirect doesn’t work for the individual post pages since I am using javascript to direct the user to the new post (based on the title). It probably would be a good idea to throw in the META redirect as a backup though, so that non-javascript users would at least get to the new homepage. Good suggestion, Thanks!
