I moved my adahs to a new tray, a few inches from the original position. I also moved the GPS two feet to the front of the aircraft (a few inches lower than before). I am trying to find any info on how to (if needed) to re-calibrate the two items. Thoughts?

The ADAHRS setup has the offsets. I don’t think the GPS has an offset, except in the ADS-B Out setup, which is pretty coarse.

As RVDan says, the ADS-B Out setup has some positional information stored, but it's coarser than what you've changed.

The only calibration that would be affected by the ADAHRS move is the magnetic heading calibration, as its proximity to surrounding ferrous metal and current-carrying wires/devices may be different. If you have the SV-MAG-360 remote magnetometer though, those sensors override the ones inside the ADAHRS, and then you wouldn't need to do anything here.
