Introduction:
The purpose of this
article
is to
describe the failed over practice and strategies that are
effective during a migration process from Exchange 5.5 to Exchange 2003. This
documentation is not for fault tolerance. The purpose of the
article
is to
give to the network administrators the capacity to properly roll-back a failed
migration process. Also, during the planning and design process to properly
understand how to step back. Helping the network administrators understand the
importance of planning the detailed procedures of the migration and to follow specific
operational guidelines for restoring data in case of failures.
Move Mailbox and how to Roll-Back in case of Failure:
Cross-Site
Migration Method:
The
process will outline the steps required to migrate mailboxes, distribution
lists, custom recipients (contacts), and public folders to the central site

swing-methodology and Exmerge.exe can become important tools in case of failed-over
also.
