Hello,It doesn't look like an upgrade is possible from Windows 2008 Standard (Full Installation) to Windows 2008 Enterprise (Full Installation). Possibly from core to core... It is hard to understand the upgrade path listed at this link:http://technet.microsoft.com/en-us/library/cc755199.aspx as there are no specific instructions on how to accomplish this. The table shows - Windows 2008 Standard Windows 2008 EnterpriseIt does not specify "Full Installation" like it does in the others.Anyway, I have tried upgrading from Windows 2008 Standard 64 bit to Windows 2008 Enterprise 64 bit and have been unsuccessful in the following ways:1) Booting off the Windows 2008 Enterprise DVD and trying to select "Upgrade". Setup kindly responded by saying to rebooting and run Setup from within the existing version of Windows.2) Ran Setup from within Windows 2008 Standard by inserting the DVD and selecting to install.... When the Upgrade option appeared, it was disabled (grayed out). Comments say -Upgrade has been disabled- The upgrade can not be started. To upgrade, cancel the installation andthen choose to upgrade to a version of Windows that is more recent than the version you are currently running.How do I do this?I am trying to take advantage of more RAM in the system and not have to reinstall everything, it will take hours.Thanks.Dane!

Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights. The server(s) do indeed have Service Pack 2 installed. I will unstall and try again. I will post the Help->About to be complete -Version 6.0 (Build 6002: Service Pack 2)Is that the complete version? Thank you,DaneDane!

Ok, SP2 is uninstalled. The description shown in Add/Remove programs (Program Features) does not say Windows Service Pack 2. I thought that was SP1, when I didnt see a SP2 listed I checked the KB article numeber listed next to the description and it took me to SP2.Cool.Upgrade is now enabled when running setup from within Windows, looks like it is working. Odd how SP1 doesn't conflict with the upgrade.Thank you,DaneDane!

Ok, this seems to have worked out pretty good so far.A couple tips of advice -1) I had teamed up NICs using 802.3ab link aggregation. You should remove any teamed NICs before upgrading, I had to reinstall the software anyway.2) It might be a good idea to uninstall any Operations Manager host monitoring service(s) and reinstall them after the upgrade. This will also update the OM inventory at the same time. I seen them crash during the upgrade process but have 4 servers upgrading at once in different stages so I'm not sure where/which crashed.I'll consider this as resolved. Thanks!Dane!

The RTM version of Server 2008 was already SP1. The Vista SP1 came out before RTM of 2008, and 2008 included this code at RTM. A similar situation with Server 2003. XP was already at SP1, but in that case they did no call the release version of Server 2003 SP1. This lead to the odd situation where SP1 for the server corresponded to SP2 for the client OS. With Server 2008 they called the RTM version SP1, so that SP2 for both server and client arein sync.Bill
