The last couple of weeks I'm staying in a hotel in The Hague to help a (pilot) migration to Open Source at the Octrooi Centrum Nederland. But now we can finally share some results (in Dutch).

To reiterate, we have:

• All storage is Linux based (SLES)
• CMS is migrated to Joomla
• Application server are Linux (with Xming this will also work on Windows).
• Active directory is connected to a MIT Kerberos server. Synchronization works with a massive shell/Awk script.
• And now also Zarafa! Zarafa is a open source (GPL) Exchange replacement. Now we can just fiddle with /etc/postfix/main.cf instead of the some weird registry foo.

I must say I'm impressed with Zarafa, Campai and the IT staff at Octrooi Centrum as they were a tremendous help in implementing this.

Some other stuff I discovered during this migration:

• LVM: good, LVM snapshots: bad
• nss-ldap
• Linux networking bonding

There is still a lot to do and document. Sometime next year AT Computing will publish a white paper (or several white papers) which document this migration.
