FILIPP I was looking for a way to easily move local iCal (v 3.0.4) data to the company's iCal server. You can do it pretty easily by just moving the local ics files and deleting the cache, but iCalCopy was much nicer and I didn't even have to close iCal!
Would be worth 5 stars if it had a better UI in terms of differentiating between local and remote calendars (they just show up as one flat list and the only way you can distinguish them is the order they appear in iCal, if you have similar names).
Many thanks to the dev! ;)
