Migration PST -> Kolab

[Younex]

Hello!

I´m migrating from Exchange to Kolab.
The Server is online and Kolab ist installad, everything is working.
Now i want to migrate my old *.pst file from Outlook (Mails, Adressbook,
Appointments,...) to Kolab.

Does this way work:
Start Outlook an connect via the Toltec-Connector to the Kolab Server.
Does Kolab sync automatically the data from the client?

If yes, what sizes of *.pst files can kolab handle?
I mean, does the performance dramatically decrease with big databases or
is it stable (up to 5-7 gig pst filez...)

Thanx in advance,
Younex
