Mike, thanks for your reply (you too, Simon).  I'm honestly trying to understand what's going on here.

Both kronolith_shares and horde_datatree exist as tables, but neither has any records.  

[root at webmail docs]# echo 'select count(*) from kronolith_shares'  | mysql -u horde -p horde
Enter password:
count(*)
0
[root at webmail docs]# echo 'select count(*) from horde_datatree'  | mysql -u horde -p horde
Enter password:
count(*)
0
[root at webmail docs]# echo 'select count(*) from kronolith_events'  | mysql -u horde -p horde
Enter password:
count(*)

The only rows I'm finding on our mysql database for kronolith shares look like this:

INSERT INTO `horde_prefs` VALUES ('user at acd.ccac.edu','kronolith','default_share','user at acd.ccac.edu');

In other words the pref_value always matches the pref_uid.   However only a fraction of calendar users has such a row.

I agree that datatree is enabled, but I'm missing if or how it is being used.   The 
kronolith-convert-datatree-shares-to-sql will seemingly find nothing to convert.  I've
tried running it and it didn't make any difference in my upgrade attempts.
