I work for a group that is constantly moving shapefiles into Petra as overlay files and out of Petra overlay files into shapefiles. As it stands we are able to move the shapes but not the attributes when converting in either direction. It seems like I have been searching for a good answer to this question for some time and this post from 2007 indicates that others have been looking for good solution as well. My questions then are:
1) Is there a method / tool to convert to and from Overlay Format and Shapefiles that preserves the attributes?
2) Is this a scriptable (python) process?
3) Does anyone have experience with a Petra - ArcGIS workflow that they feel is successful?
