How to upgrade sites to Plone 5
With the release of Plone 5 everone starts thinking about if, how and when they should upgrade existing sites to Plone 5. In this talk I will discuss upgrades in general and especially those from Plone 4 to Plone 5. I will cover the important analysis- and planning-stages of every upgrade, the code-aspect of upgrades and some of the many pitfalls that can befall you during migrating. I will devote special attention to migrations from Archetypes to Dexterity.
