Hi,

the trick is to use package dbms_space_admin (Cf Oracle Doc) to convert from DMT to LMT.
With this method, you obtain a "USER" allocation type as seen in dba_tablespaces view that allow you to use maxextents clause.

N.B. to ease the conversion, it's better to have DMT tablespaces already using "minimum_extent" clause

Hope this helps
