Changing iTunes U feed URL

Question

Hello,
we have to modify the the feed URL's for our existing collections on iTunes U Public Site.
Feeds are hosted by our server ( not Apple Server hosted feed).
  What I'm thinking to do is to delete existing collections via Public Site Manager and then re-add the collection with the new feed URL.
Is this the correct way to modify the URL feed ?
Any suggestion is welcome.

I was faced with the same problem (see below why). Here is the best fix I could come up with:
1) For each affected podcast, drag all 'old' episodes to the Desktop. If you want to keep the playcount and rating, note them down or best take a screenshot.
2) Delete the podcast and all associated files from within iTunes.
3) Subscribe to the podcast again via the publishers website or the iTunes podcast directory.
4) Drag all audio files from the Desktop into onto the podcast window in iTunes. Manually set rating and playcount again.
Step 3 probably is not necessary but I could only test this with one podcast. Somewhere else in this forum, a Windows user noted that she or he was able to edit the URL of the podcast in a file found in C:\DOCUME~1\USER\LOCALS~1\TEMP\ circumventing the workaround described above.
This problem was affecting all my podcasts because of some stupid oversight by essentially Apple. I was using a wireless access point in a hotel, where you first always get redirected to the providers site and login from there. Pretty common. I, unwisely as it turned out, updated my podcasts there, which worked fine at that moment.
Being home again, all my podcast URLs started, as seen via right-click: Show Description, with http://www.arrowlink.com (...), the name of the access provider, I could even see the name of the hotel as part of the URL. Evidently, iTunes did not consider these URLs as valid.
