What are some best practices for ArcGIS v9.3 and v10 in the same shop?
We have a couple of dozen users on v9.3. The bulk of our data is in file geodatabases and geotiffs, with a respectable splash of shapefiles and occasional jaunts to ArcSDE (v.9.3.1) hosted by another department. We will be introducing v10 to the power users first and for an unknown period of time, likely 6 months, the two will be operative at the same time. All of the data as well as map compositions, layer files, symbol styles, etc. will be used by both groups.
How do you structure things so these two sets can peacefully co-exist? What are the things to watch for?
