Well, can report that I made sure that the old feed url sends a 301 
(permanently moved) to the new feed url.

However Planet doesn't like this:

Feed returned redirect (http 301)

And marks the request as "Failure".

Looks like the new feed url must be updated (and then the blog goes into 
review).
