EDI Mode in Intergration Builder : Design

Hi All,

Presenly, we are upgrading my PI 7.0 system to PI7.3. We are doing in all the 3 systems(DEV, QUALITY and Production).

We arleady upgraded our development system and testing is going on. We've planned to complete this upgrade project in another 2 months. We need to do a change in one of the MAP immediately. Presently the in Quality system the "switch between Dispplay and Edit mode" icon has been greyed out(disable mode).

Is there anyway to do the map change directly in PI7.0 and move that to PI7.0 production system? If yes, please let me know the details.
