I need to transfer my database from Oracle 11gR2 to 12c database. It will be in same computer. I took full backup of Oracle 11gR2 database. Then I remove Oracle 11gR2. I installed Oracle 12c and I tried to restore my backup. I could restored spfile, controlfile, datafiles.. But I couldn't do
RMAN> ALTER DATABASE OPEN RESETLOGS; ORA-01092: ORACLE instance terminated. Disconnection forced ORA-00704: bootstap process failure ORA-00604: error occurred at recursive SQL level 2 ORA-00904: "I". "UNUSABLEBEGINNING# ": invalid identifier Process ID: 3377 Session ID: 125 Serial number: 5
What should I do to open database? Should I do Pre-Upgrade script ? I couldn't understand to do pre-upgrade script step..
