1) Create a new tablespace
2) Move all the object from BIG to normal tablespace
The option BIGFILE cannot be altered to SMALLFILE. So you should create a new Tablespace.
Before moving your datas, be ensure that you have enough capacity in this new Tablespace. So
plan to get enough place on your server.
After moving the content of the Tablespace (it can be done for instance by DataPump)
you could DROP the BIGFILE Tablespace and RENAME the new SMALLFILE Tablespace
so as to keep the original name, as follow:
Hope this help.
CREATE SMALLFILE TABLESPACE <NEW_TBS_NAME>; --> Move or export/import the content DROP TABLESPACE <ORIGINAL_TBS_NAME> INCLUDING CONTENTS AND DATAFILES; ALTER TABLESPACE <NEW_TBS_NAME> RENAME TO <ORIGINAL_TBS_NAME>;

In addition to the answers - you cannot simply convert the tablespace - why do you want to do that. What is so bad with your bigfile tablespace?
