We have an old installation of the Sugar OpenSource suite, version 3.0.1b and are looking into upgrading it to current.

I notice on the sugar download site all the upgrade packages start at sugar version 3.5.

Are the upgrade packages for earlyer versions available, and is there any possibility of a 1 step upgrade from 3.0.1.b to 4.2.1. Or is the only option to completely reinstall sugar and try and export/import what data we can salvage?

Thanks
