Migrate Oracle 9i mission critical database to Oracle10g

Hi,

We are planning to migrate our mission critical database from 9i to 10g. This database cannot be shutdown for a single minute and we cannot afford to loose any minute data.

 

My interest is , How would I migrate without shutting down the database.My understanding is that the our 1 terabyte database needs to be cloned using one of the following methods

 RMAN, EXPORT/IMPORT, DBUA, CTAS or Manual (OS level copy of data files) of upgrade

But all the above methods require downtime. Please correct me if I am incorrect here.

 

I am guessing that any major financial organization would like do this on the fly (without shutting down the database).
