First of all, which "Galaxy Pro" are you referring to? Samsung makes a 12.2" inch/10.1" inch/8.4" inch Galaxy Tab Pros.
The Tab Pro 10.1 is 171.4 x 243.1 x 7.3mm
The Note 10.1 is 171.4 x 243.1 x 7.9mm
In terms of thickness, the Note 10.1 is thicker than the Tab Pro 10.1, so one case wouldn't fit the other properly.
