Few limitations with LMT:

1) Minimum datafile size is 64K.
2)While creating datafile, be sure of extent policy.
3)Do not drop in read only mode.
4)Rollback segments are first created on dictionary tablespace and then coverted to LMT, besure compatible parameter is 8.1.6.
otherwise, Full export will give u problems.
5)Next extent,pctincrease parameters do not work.
6) Cannot change next parameteronce objects are created.
