Mariono Gomez and Mohammad R. Daoud have previously covered Upgrade paths to GP 10 from older versions
While they come up with their lists, here is the upgrade path to GP 2010 that I know of.
From GP 9 – Required 9.00.0371 (Hotfix KB 971017) or later (GP 9 SP 4 was 9.00.0352 )
From GP 10 – 10.00.1368 (Service Pack 4) or later
NOTE: There is no direct update from Microsoft Business Solutions-Great Plains 8.0 to Microsoft Dynamics GP 2010. You must update to Microsoft Dynamics GP 9.0 or Microsoft Dynamics GP 10.0 first.See the Updating to Microsoft Dynamics GP 2010 hot topic
