Whats is the procedure for changing the primary index for a table which is enabled for Q replication. Q replication is using the current primary index for that table to enforce the uniqueness. And that needs to be changed.

Can anybody help me out with the procedure ? Do I need to drop the q sub, drop the old Primary key, create the new Primary key and recreate a new q sub by stopping the application? or is there any other shortest way to accomplish it ?

Have a look at this page .. I am sure you will find pointers
