Thanks Suresh.. But I cannot do an local with autoallocate of 8k in initial extent size.. Autoallocate starts at 64K.. You are right about space.. My db is fully furnished and I want to do this now since I realised lots of space is wasted as 85% of the tables have 0 rows... That is the reason, why I want to convert. Would any Sr. DBA's explain the process please..

Thanks, ST2000
