2. Replace the Directors.
3. Install Enterprise pools and Standard Edition servers.
4. Install Archiving and CDR Servers as necessary.
Why? Again, it??™s the logical progression. Replacing and installing servers in this order is
supported. Not following this process means that fi les won??™t be installed in the proper order.
At this point, you should have some users test the behavior of IM and presence in the
new environment. At this point, you have two operational installations: one Live Communications
Server 2005 and one OCS 2007. Move the users from the Live Communications Server
2005 installation to the OCS 2007 and have them test IM and presence information in the
MOC 2007 client. After you??™re sure that IM and presence are working correctly in your new
environment, you can deploy Web Conferencing Edge Servers and A/V Edge Servers in
your perimeter network. After you??™ve made sure that Web conferencing and A/V conferencing
are working properly, you can move the rest of your users to the new deployment and take
the Live Communications Server offl ine.
Remember, planning your upgrade to OCS 2007 should include the following:
?– Understanding the basic migration process
?– Understanding coexistence issues
?– Planning user migration
?– Determining your requirements for additional hardware
Before you begin either your deployment or your upgrade, you need to spend some
time with the OCS 2007 Planning Guide. It goes into considerable detail concerning each
step for new installations.
