Good day everyone. We are looking at upgrading Exchange and Windows server OS on a few boxes and would like to know if there are any potential issues we could experience. We will be upgrading our Exchnage 2003 (Windows Server 2003) machine as well as our PDC which also houses Trend Micro network protection, and our customized accounting software.
All our client PCs run Office 2007 and will be upgrading to 2010 after the upgrade to Exchange 2010. All the computer also run a minimum of Windows XP with many on Vista and 7. We also have a BES server on v.188.8.131.52 running on Windows 2003 as a third server and have a Secondary DC which is also our file server running Windows 2003 as well.
If we were to only upgrade Exchnage to 2010 and the Primary DC to Windows 2008 R2, are there any known issues that could experience over all?
