Migration Wizard does not provide you with the means to migrate
groups or distribution lists directly from a messaging system other
than Exchange. There are two basic strategies for updating
distribution lists: you can convert them to public folders and
migrate them, or you can export them and then import them into
Active Directory using the LDIFDE or CSVDE command-line
For more information about maintaining distribution lists during
migration, see Microsoft Exchange Server 2000 Planning and
To move users from distribution groups to public folders:
Add a rule in each public folder to forward all new items to
all members of the distribution group who have mailboxes that have
not migrated to Exchange.
On the public folder, give user permissions to all Exchange
members of the corresponding distribution group.
When the name of the public folder is visible in the existing
system, remove the corresponding distribution group.
To migrate groups or distribution lists:
Export the lists from your current messaging system. (For
example, use the Export.exe utility for Lotus cc:Mail.)
If you need to match or update groups that already exist in
Exchange, from System Manager, select the organizational
unit that contains the group or groups that you want, click
Action, and then click Export List.
Use the LDIFDE or CSVDE command-line utilities to import the
groups into Active Directory. (For more information about the
utilities, see the Windows 2000 online documentation.)
