Best practices for Deferred Defects?

Hi,

I am wondering what are the best practices for the Deferred defects from a particular Release cycle "X" which needs to be considered in following Release cycles "Y" and "Z". In order to get a holistic view in any of the particular releases, how do teams track these deferred defects?

1) Does the "Detected in Release/cycle" gets change from Release "X" to "Y" and any new defects identified from Release "Y", will create a holistic view for the management?

2) Or do we update the "Target Cycle" to Release "Y" and make sure any new defects identified from Release "Y", will also has the target cycle set as "Y" in order to get a holistic view?

Kindly share your experiences and best practices which can be followed here?

Thanks a lot.
