I am a newbie. I am currecntly trying to assess the risks involved in trying to upgrade a windows 2000 server to server 2003 version. This a real time database server with oracle 8i and is running on windows 2000 version. I have read in one of your reponses that 8i is not supported on win 2003 server. The least it requires is 9.2 and above versions of oracle. Elseweher it is said that 9.2 is unsupported as well and hence it is good idea to go 10g/11g. Since win 2000 is soon going to be unsupported by Microsoft it is of paramount imp to upgarde the srevre to 2003. My question is how best or least risk is it to upgrade to 9i? is there similarities between 8i and 9i or will be a completely unsupported? Any suggestion will be greatly appreciated.
