I'm creating a new point FC from an existing point FC. I have 600,000 address points in my database and a department a my work wants their own service point FC using the address point FC as a template. The catch is they don't want them to overlay the address point FC on the map. My question, how can I do a mass shift to slightly move the position of these new service points off of the existing address point I copied them from?

You could load your data, and perform a spatial adjustment.

Your could edit your points, and use "Move" to offset them.

If you have some experience with arcpy, here is a snippet of code that may help you:

Shifting features

Shifting (or moving) features is a snap using the arcpy.da module’s UpdateCursor. By modifying the SHAPE@XY token, it modifies the centroid of the feature and shifts the rest of the feature to match. This approach will hold for point, polyline or polygon features.

To modify only a single or subset of features in a feature layer, apply a selection to that layer and pass the layer in as the input to shift_features.

Word of caution, this is using UpdateCursor, so features will be permanently modified. So, back up your data if you may potentially want to reverse the updates.
