7.31.UD8 migration to 10.00.UC4 failed with :Con/rev: Failed to convert for Component SQL

Hi Gang, During a migration from 7.31.UD8 to 10.00.UC4 I ran into the following error during the conversion : Con/rev: Failed to convert for Component SQL. Then the engine crashed and had not been able to bring it backup due to corruption in sysmaster. Since it was a test env, I restored the environment and restarted. For a second time it failed for the same reason and same place. Any help or thoughts would be greatly appreciated.
