To best explain this is to Understand the Key Differences Between Notes/Domino and AD/Exchange.
The fundamental architecture and functionality are different between Notes/Domino and AD/Exchange. It is inevitable in any migration that some features or data elements in the source environment have no comparable counterparts in the target environment, and Notes-to-Exchange migrations are no exception. A listing of such known limitations appears in Appendix A of the Quest Notes Migrator for Exchange 4.1 User Guide found on the Quest Notes Migrator for Exchange product page on Quest SupportLink:
Migration planners should understand these significant differences between the Notes/Domino and AD/Exchange environments:
- Exchange is more specifically oriented to email and calendaring functions, whereas Notes supports broader collaboration and other functions including mail-enabled work-flow applications, and an internal scripting language that can be used for various functions including customized application development.
- Exchange relies on Active Directory for its members (the Global Address List), whereas Notes is its own directory.
- Notes uses individual files per user for different types of data, while Exchange uses a central mail database and address book. Only personal archives are separate files in Exchange.
- Notes permits the making of data-file replicas, both locally and on the server.
- Some of the functionality of Notes applications can be mimicked with SharePoint.
