Messaging and collaboration systems have become unavoidable parts of enterprises. They help organizations in collaborating effectively to improve efficiency, and to increase productivity. Today, organizations have choices like MS Exchange Server, IBM Domino, and Novell GroupWise for messaging and collaboration systems. The choice of a messaging and collaboration system by an organization usually depends on the requirements of the organization, its infrastructure, and cost considerations.

Is it necessary to migrate from one platform to another?


Yes, sometimes it is. Usually investment on the infrastructure messaging and collaboration platforms is considered for long term. But when there are mergers or acquisitions between firms that are using different platforms, or when a company is in need of a more suitable platform than the present one, migration from one platform to another becomes essential.

Exchange to Domino migration – what are the advantages?


Exchange Server, from Microsoft, is the most popular of all messaging and collaborations platforms. But Domino/Notes form IBM has its own advantages. Exchange Server is designed for Windows environment. But IBM Domino supports Windows, OS X, Linux, AIX and Solaris. Also, IBM domino supports hardware and software virtualization, and offers some complementary products along with it. With its application level clustering, it is more flexible and dependable. Also, many organizations choose Domino considering its low operational costs.

File formats used by Exchange Server, Outlook and Domino


Exchange Server stores its data in Exchange Database (EDB) files and Streaming Database (STM) Files. These two files together from Exchange store repository. The EDB file tables mainly contain metadata of email messages, MAPI messages and attachments. At the same time, MS Outlook, the client of Exchange Server, stores its email messages, calendar, tasks, and other items on your system as Outlook Data file (PST).
IBM Notes database uses Notes Storage Facility (NSF), an IBM proprietary file format, for storing its Notes information such as data, metadata and design information. Notes mail stored on Domino Server, and address book database stored on user system are in NSF format. The NSF files are read both by the Domino Server and the Notes client.
