Move calendar entries to a different folder in bulk?

I imported my calendar from Windows Live Mail into Gmail and so now have calendar entries in two different folders. I see that I can open a calendar entry and change its folder, but is there a way to move multiple calendar entries? Can it be done as a cut and paste to avoid duplicates? Thanks.

You can simply open the Agenda view, select multiple events and copy them to a different calendar. Then you can simply delete the original events to avoid duplicates.
