Can i reverse the Snote

I had implemented Some notes in Development system.

It is having Some Extra Screens, these screens are added to the already existing one, If i press button, Newly added screen may comes.

It is having Source code and dynpro , Some other settings.

Imagine i moved the changes to the Quality Server, Now can i Rollback it.

I Checked in forum, I got some mixed response, that Some are saying not possible, some are saying possible.

Need your suggestions.
