Hello Adapt,
I have recently tried to upgrade with no success. Here's what I've done and hopefully someone can shed some light.
1. deleted the node modules folder
2. ran "node install --production"
3. node upgrade.js
Running this successfully upgraded both framework and authoring tool but when I access the portal through the portal, It still renders the old version but also breaks preview and other elements. is their a known issue? the current version was 2.0.7 for the framework.
thanks,
