Don't believe that!
At first, have a look at slapcat / slapadd. Then create a test user on your 
Kolab 2 system. Compare the LDIF content to the Kolab 1 installation. Take 
care for differences. Write a little Perl script to tweak what's needed.
Then do something like: 

slapcat > old.ldif
cat old.ldif | your_script > new.ldif
slapadd new.ldif

I've migrated 50+ users without to enter them manually, however my Perl 
script is of course specific for our environment. So it won't help you.

To keep the e-mail, you can copy them from the old to the new system (but 
you would need to rebuild the indexes afterwards, which might be a pain). 
This is the way I did it.
You can let the users move them from the old account to the new one (given 
you can run both systems in parallel). Or you can use an IMAP sync 
solution. IIRC you would need to know the passwords in that case. Search 
the archive of this mailing list for details ...
