At my job, I have been given the task of upgrading our Oracle 8.1.6 databast to 9.2. This is on a Windows NT 4.0 box and I did the original install of 8.1.6. Can I just throw in the 9.2 CD and do the upgrade with minimal risk? I do have backups of the database and I am not a true DBA, so this is new to me.

Any help would be great!!

Thanks
