Zentyal is an open-source Linux server solution for small and medium businesses that provides file sharing, communication, and other IT infrastructure capabilities. It can replace Microsoft solutions like Windows Server, Exchange, and Lync. The document discusses Limerick City Council's migration from Microsoft to Zentyal and Zarafa for 450 desktops, reducing licensing costs. Their migration process involved phasing departments to Zentyal over time while maintaining integration with Active Directory. They have now migrated 99% of users to Zarafa email and are working to phase out Exchange completely.

Communications with staff: buy in is key
Training for staff and IT support
