Loading CalDav calendars

[Nic Bernstein]

Friends,
We're finally starting to play seriously with the CalDav implementation 
in Cyrus 2.5.10.  We've flirted with it in the past, having been 
building our own packages from the 2.4.x+caldav-beta lines for years, 
but now we're trying to actually move from our old CYrus IMAP/DaviCal 
combination to just Cyrus IMAP.

The CalDav support seems to work fine with our clients -- 
Thunderbird/Lightning, Android, etc. -- but while we can use Cadaver to 
pull perfectly good ics extracts from our old DaviCal server via 'get' 
and 'mget' operations, we are unable to upload those to Cyrus with 
Cadaver.  Here's what we see:

We really don't want to lose the event histories we have in the 
calendars, some of which are >1k entries long, but cannot find a good 
way to get the data into Cyrus.  Could we do so by simply dumping the 
ics files into the mailbox directory, running a reconstruct and restarting?

I've tried using Lightning's import function, but it barfs after a few 
hundred entries, leaving the collection in an unusable state. The only 
sure-fire way to recover from that is to blow away and recreate the 
collection.  Obviusly a suboptimal solution.

We had even worse luck with Evolution, which wouldn't import at all.

Any ideas?
