Upgrade SugarPro 6.5.18 to 7.6.0

Hi,

We want to upgrade our Sugar Prof. Currently, its running on 6.5.18. Can we upgrade it to direct with available package SugarPro-Upgrade-6.5.21-to-7.6.0.0.zip ?

Or if we need to update latest 6.5.x then how we can do that?
I checked only this package available on SugarPro-Upgrade-6.5.x-to-6.5.22.zip.

Please reply. Thanks
