Optimal Strategy for upgrading to 10.x geodatabases

Hey everyone,

What is the best way of upgrading 9.2/9.3 geodatabases to 10.x?

In my mind, I can either:

• Use the built-in "Upgrade Geodatabase" tool
• Create a new 10.x geodatabase and use FC to GDB to copy from one GDB to the other.
• Take the original shapefiles (where available) and use FC to GDB to convert everything to FC's

My gut would be to simply use the Upgrade Geodatabase tool, but I was wondering if this would always be the case.

Thanks a bunch!
