Completed Your Migration to OCS 2007
Once you??™ve migrated your servers from LCS 2005 to OCS 2007, you can take advantage of

online or offl ine status information, but also with integration with Outlook
calendaring data.

multipoint video conferencing, which are enhancements to OCS 2007.

Summary
Migrating from LCS 2005 to OCS 2007 requires that you follow certain steps in a certain
order. These steps comprise installing new OCS 2007 servers into the environment, integrating
the new servers into the new environment, and then removing old LCS 2005 servers once
the new OCS 2007 servers have successfully taken the place of the LCS 2005 system.
When migrating, it is a best practice to start from the outermost servers and work your
way in to the internal servers. In the side-by-side migration process, you install new OCS
2007 edge servers in place of old LCS 2005 access proxy servers; replace old LCS 2005
director servers with new OCS 2007 director servers; and add new OCS 2007 front-end
servers and move users from old LCS 2005 front-end servers to the new OCS 2007 servers.
