Exchange migration - the final steps

[Gustavo Michels]

For e-mail, you could use imapsync, a perl script for mass migration using 
IMAP servers. The downside is you'll need a list with the users and 
passwords for both systems (exchange and kolab). There's a way to gather 
a list of AD users, but for passwords, there's no other way than 
resetting all user's passwords to a known one. Well you could use some 
tools like pwdump2 and lophtcrack to crack the SAM database.

You may go another way: use exmerge and use some tool like readpst (part 
of libpst) to extract the e-mails and upload them to cyrus imap. For the 
upload you'll need to create a little perl or python (or whatever) script 
to do the job, but you'll still need the password for the kolab part.

For any other groupware data (calendar, contacts, etc), the hole is much 
deeper since there must be a format conversion. I have created some 
python scripts for a university project which will convert the exchange 
data to kolab xml, but they are far from perfect. The process is too 
complex and somewhat dependent on steps of the original project I was, so 
maybe they aren't useful for everyone.

cheers
