Hi Tyfanie, I believe I have the same problem, but I am migrating between 11.1 and 11.2 on Linux 64 bit platfom. I tried a couple of time to migrate and one time the asmca failed the other time it said it worked, but in fact failed. In the ASM alert log I see the error: ORA-00600: internal error code, arguments: [kfeInvokeLockCallback06], [30], [], [], [], [], [], [], [], [], [], [] ORA-15240: attribute name SAGE_ONLY is invalid Basically the ASM instance shutsdown, but the OUI does not recognzie this and blindly stumbles on outputing "Oracle not available" in the logs. I have an SR open with Oracle but so far no response. Also I started a thread on the list last week and a patch was suggested, but I thought I should go via Oracle Support to be sure! I would be interested to know if you see something similar in your ASM alert log. One other thing, having the environment variable ORA_CRS_HOME set to the original CRS home will also break the migration, because the wrong crsctl programme gets called, assuming of course you are on a *nix platform.
