What is the expected downtime duration ?
What is the database size ?
For a "small" database with no downtime constraint you could use Data Pump to move data.
For a "large" database with minimum downtime you could use Oracle Streams (with Enterprise Edition) or Golden Gate (separate product: needs new licensing).
You can find detailed migration/upgrade recommendations and scenarios on OTN database upgrade page:

thanks alot for your time and help !!!
Our Database is too large and no down time , so we decided we will done this process by Replicate machine. Which is in sync through Goldengate.
Yes we can through Goldengate initial load approach. question is will it good approach because our database will be near to 5-6 TB. Might be it will take lot of time
There is any another approach....
