All your Exchange 2007 servers should be upgraded to SP2 first, which requires the SP2 Schema extensions.
You'll want to run the Exchange Pre-Deployment Analyzer prior to trying to upgrade: http://www.microsoft.com/downloads/details.aspx?FamilyID=88b304e7-9912-4cb0-8ead-7479dab1abf2&displaylang=en Chuck Robinson _______________ Solutions Architect MCITP:EA, Messaging / MCSE: Messaging EMC Consulting Mobile: 973-865-0394 chuck.robin...@emc.com<mailto:chuck.robin...@emc.com> www.emc.com/consulting<http://www.emc.com/consulting> Transforming Information Into Business Results From: Al Rose [mailto:arose...@gmail.com] Sent: Friday, May 28, 2010 12:17 PM To: MS-Exchange Admin Issues Subject: Coexistence 2007 and 2010 - introducing the first 2010 server - schema Hi all, My company is currently running a mix of MS Exchange 2003 and 2007. The first E2k7 servers have been installed from the first Exchange 2007 version release media (No SP1 or SP2 at that time), so the schema was upgraded without SP2 and therefore I would like to get confirmation from you whether or not a schema upgrade is needed to install the first Exchange 2010 server. Thanks in advance. Al.
