Drop Partitioning

We have a test box that we want to remove partitioning from. does anyone have the steps to retain table data while dropping the date range partitioning. My first thought was the following. please correct me where I go astray:

1. export the table data
2. create similar table in the same tablespace with the appropriate constraints/indexes
3. insert into <new> as select * from <old>
4. alter table <old> drop partition
5. drop table <old> cascade
6. alter table <new> rename to <old>

 Thank you in advance for your help and expertise...
