I am trying to upgrade from OC7 to OC10. I understand that I have to step through every major upgrade.
My problem is that the two most important apps for us are calendar and contacts - both of which are now 3rd party apps. Worse, trying to install them from git for the steps from 8.0 to 8.2 seems like a real pain.
Can I safely upgrade through the 8s without installing these apps? Once I get to the 9s I can use the marketplace.
