Migration is the process of moving your existing messaging
system to Microsoft Exchange 2000 Server. Migration involves
exporting a copy of your existing mailboxes, messages, and other
data, and then importing that information into Exchange. Your
primary tool is Migration Wizard.
You can use the wizard to migrate directory and message data in
one step, or you can migrate to a set of migration files first and
then use the wizard a second time to import the files.
Regardless of how you use the wizard, your overall migration
process can happen in a single phase—that is, you can move
the entire organization at once—or more likely, you will use a
multi-phased process that requires a period of coexistence.
You can extract directory information and mail
data using one of the source extractors that are provided on the
Exchange CD in the Migrate folder. Additional stand-alone
extractors are provided for Microsoft Mail for AppleTalk Networks
and IBM PROFS, NetSys (formerly Verimation MEMO), and Digital
ALL-IN-1 host systems. These extractors are not integrated into
Migration Wizard, but after extraction, you can use the wizard to
import the extracted files. In addition, you can create your own
source extractor. More...
Exchange provides a suite of tools, called connectors, that support coexistence with
other mail systems. For information on planning your migration and
developing a coexistence strategy, see Microsoft Exchange 2000
Server Planning and Installation. More...
There are several ways to control which
directory and mail data you migrate from your existing messaging
system to Exchange:
Prior to migration, you can edit existing data. More...
You can edit the migration files. First extract the directory
information (the first step in a two-step migration). Then
edit or delete the migration files. Finally, import the edited
files (the second step in a two-step migration). More...
Migration Wizard screens provide custom controls so that you
can select which mail data migrates. More...
