Hi Folks, Kerry from Support here. If you are upgrading your Windows 2008 R2 server from 22.214.171.124 to 126.96.36.199 and your install is NOT on the C: drive please make sure:
1 - you don't have any dbf files in $ORACLE_HOME - if you don't know how to check, open a support ticket and we will help you
2 - Make a backup copy of your ORACLE_HOME with the database down - this is critical as it is possible in some cases that ORACLE_HOME gets lost
feel free to open a support ticket to discuss!
