Hi, I took a cold backup of 9i datafiles and copied them to the new 10g 64-bit server I installed the 10g 64-bit Oracle Home On the new 10g server, I recreated the controlfile to point to the new location of the datafiles and ran SQL> startup upgrade It failed saying that database should be open in resetlogs or no resetlogs mode I shutdown the db and did a startup mount and SQL>alter database open resetlogs; This time it failed saying that database should be opened in upgrade option. I am unable to proceed with the upgrade. Anyone ever faced this issue? Regards, Ashwin
