RMAN Duplicate failing

I am trying to duplicate a 11.2.0.3 database but it is failing with the following error. I was successful in doing RMAN duplicate of the same database when it was at Oracle 10.2.0.4.

I didn’t enable ‘BLOCK CHANGE TRACKING’ feature in this database.

Q1. If it was enabled while it was still at 10g then why the duplicate worked fine at that time and failing now when the database is at 11g?

Q2. Does the upgrade scripts automatically enable ‘BLOCK CHANGE TRACKING’ feature while upgrading the database from 10.2.0.4 to 11.2.0.3?

Q3. Is there way to verify when and how ‘BLOCK CHANGE TRACKING’ feature was enabled?

Q4. If statement in Q2 is not true then what are other means of enabling ‘BLOCK CHANGE TRACKING’ feature?

Q5. As per some Oracle note it recommends to disable the feature and then run the RMAN duplicate but even after I have disabled the ‘BLOCK CHANGE TRACKING’ RMAN duplicate is still failing the same error.

Q6. Any idea how to address this issue?
