Now that DevTest 10.1 is GA, attached is an upgrade guide that will take you thru the steps and the important considerations for the upgrade to the latest and exciting release of DevTest.
Here is the location of the PDF - How To - Upgrade DevTest 8.x To DevTest 10.1
Remember we now support in-place upgrade from 8.x to 10.1 which means you can install in the same location as your prior release and you can also use you existing database which will be upgraded automatically for the 10.1 release!!
Special thanks to mazda03 (Dan Mazzei) for updating the doc with the latest screenshots and new content.
Enjoy!
