Recently we blogged about the migration of our support system from Plone 3 to Plone 4. We are migrating over 100.000 objects to Dexterity. Our support site includes trackers with tickets, but also documents, instructions, and other types. Some of these types can have history. For several reason, such as ISO 9001 certification, we needed to keep the history of the objects.
Since a while we are working on our new support system. Our support system supports our workflows. It holds all our customer information, data, project information and support tickets are registered by us and our customers in our support system. Using the tickets, we can communicate with our customers and keep track of the status of the issues.
