See the brief history of Openlayers 3.x on this thread: https://groups.drupal.org/node/440733

There are no upgrade path from 2.x to 3.x. This is not due to the module, this is due to huge change in the Openlayers JS library itself.

Anyhow, when upgrading from a version to another, here are the steps with drush once the new code has been installed:

Browse the issue queue to check if the bug hasn't been already reported. There's a great tutorial on how to use it here.
Use the search function if you don't find anything.
Use the search function again.
Create an issue on the issue queue or on Github (preferred way) following the those recommandations

The old branch 2.x is minimally maintained, mostly by contributed patches and/or obvious bugs.

Pol Dellaiera: consultant, passionate guy, I love mapping stuff. I need to learn new stuff everyday !
Peter Philipp: Peter, if you read this, please send me a small introduction paragraph ;-)

This module has taken some great ideas from modules such as GMap, ImageCache, Views, and Mapstraction.
The developers and patch-providers have worked very hard to make this module what it is.
