Open-Xchange has teamed up with Pavone, a Germany-based maker of software tools for business process management, to make it easier for organisations to migrate from IBM's Lotus/Domino to Open-Xchange's Exchange-compatible open source groupware server.

As part of a wider technical collaboration, the two companies have come up with Domino2OX, which extracts user data, emails, contacts, calendar entries and tasks from Domino version 7 servers and turns it all into formats suitable for Open-Xchange Server 5.

Pavone is first making the tool available to its own customers, and the two companies will later offer Domin2OX to other system integrators, along with documentation, online help and an installer.

Open-Xchange has its roots in the world of SuSE Linux, and Open-Xchange Server 5 supports SuSE Linux Enterprise Server along with Red Hat Enterprise Linux. The company claims to have signed up more than 2,000 companies in 65 countries so far.

In July the company expanded beyond its SuSE and enterprise roots for the first time with Open-Xchange Express Edition (OXEE), built on top of Canonical's increasingly popular Ubuntu Linux, which is known for its ease of use.

OXEE doesn't require an underlying operating system, and installs through a simple interface, a plus for organisations which might not have an IT department, Open-Xchange said.
