Moving a program from side one to side two in WeldPro

[tayte2003]

I have done this on the floor but must be missing something when it comes to weldpro, maybe because I’m using userframes?
I did a group mast exchange first then a mirror image shift with rotation. The fixture is not universal so it has to rotate 180 deg. when moving from side one to side two. When trying to execute the mirror image shift. I have tried the + & - options and nothing works. Any thoughts would be appreciated!

Is my procedure wrong 1. Group exchange? 2. Mirror shift with rotation? 3. Setup calibration program? 4. Set up user frame calibration?
Thanks!
