Hi Ted,

You have to follow this upgrade path :
3.7.5 -> 3.8.10 -> 3.9.4 -> 3.10 -> 4.0 because it is recommended to upgrade directly to the latest stable release in the 3.8 and 3.9 branch.

I don't think there is a better way to achieve this task.

You can't export all classes and contents in packages : it does not work.

Good luck.

Stéphane
