Mapping Lotus Domino/Notes to Microsoft Products
Topic Last Modified: 2006-09-14
Many existing Lotus Notes implementations already have some level of coexistence with Microsoft technology such as Active Directory® directory service and Microsoft Office. Figure 1 shows the three Lotus Domino/Notes areas that should be considered for coexistence and migration environments.
Domino Directory and Active Directory
Although the Domino Directory and Active Directory serve different purposes, there is some overlap. For example, the Domino Directory stores information used when routing mail to Notes users. When these users migrate to Exchange, this information needs to be available in Active Directory. Exchange Migration Wizard 2005 for Lotus Notes creates the necessary entries in Active Directory so that mail will route to the user's mailbox.
During the coexistence phase that often occurs during a migration from Domino to Microsoft Exchange, Exchange Connector 2005 for Lotus Notes ensures that the most current e-mail address information is available in both the Domino Directory and Active Directory by synchronizing the Domino Directory with Active Directory. This information is synchronized according to a schedule and can be run on demand.
Exchange Migration Wizard 2005 for Lotus Notes performs the processes of migrating user information to Active Directory and moving data from users' Lotus Domino mail to Exchange Server mailboxes. During the migration process, both Domino and Exchange servers provide routing functionality through bridgehead servers until all users move from the Domino mail servers to the Exchange environment.
If users are hosted on both Lotus Domino and Microsoft Exchange servers during a coexistence phase, Exchange Connector provides mail routing functionality between the two disparate environments. The fidelity of the messages is maintained when routing from Outlook clients to Lotus Notes clients and from Lotus iNotes clients to Outlook clients. Mail routed from Lotus Notes clients to Outlook clients loses some fidelity due to Lotus' proprietary formatting. Calendar invitations flow in both directions and users can accept, deny, etc. using their Outlook or Lotus Notes clients.
Calendar and Scheduling
When users are migrated from Lotus Domino to Microsoft Exchange in phases, it is vital that the users are able to continue to work together during this coexistence period. Microsoft Exchange Calendar Connector 2005 for Lotus Notes allows free/busy lookups to be performed between Lotus Domino servers and Microsoft Exchange servers.
Users can perform free/busy lookups to determine the best time for scheduling meetings. Regardless of whether the users are working with Lotus Notes clients or Outlook clients, the experience does not change when querying for free/busy information of other users, regardless of the other user's client platform.
Lotus Domino applications can easily be migrated to Microsoft SharePoint® Products and Technologies (Windows SharePoint Services and SharePoint Portal Server). These applications can be rebuilt using provided templates, Microsoft InfoPath® forms, and Microsoft .NET. Each application should be reviewed to determine if the application is currently active, the security schema, the usage, and distribution patterns and purpose. Some applications may be quickly and easily migrated to Windows SharePoint Services (WSS) or SharePoint Portal Server using Microsoft Application Transporter 2006 for Lotus Domino. Other applications may be migrated to SQL, Access, off the shelf applications or existing in-house applications such as SAP. In certain situations, it is appropriate to leave the application on the Lotus Domino server and accessing this data via Web browsers or .Net.
The process of reviewing, analyzing and making recommendations regarding Lotus Domino applications is documented in detail in the Application Analysis Envisioning Process white paper, which is available from the Resources for Moving to the Microsoft Collaboration Platform Web site.
Microsoft has identified three phases in implementing migration from Lotus Domino to the Microsoft Collaboration platform:
- Planning and Preparation Understand the overall process, understand the source topology, and build a solid target environment.
- Coexistence Support a mixed topology between Lotus Domino and Microsoft. Add value to Lotus Domino/Notes by extending Microsoft functionality.
- Migration Use tools to both migrate and extend data as needed from Lotus Domino to Microsoft servers.
