We have found an issue in AJO making us concerned about how to handle emails in an always on activity - when the master email template is been updated.
It seems like there is now obvious way of changing and updating a template, and at the same time keep the content that is created in a template used in an running Journey. Changing the master template directly in prod, or from a upgrade package is no problem. The issue is how to keep the created and customized content used in that template you are updating. In many cases you are updating the "framwork" like header/footer or other more than less static content in a template. And in a Journey you create the relevant content for this activity using the "static" framework. But when you need to change/upgrade the framwork, and change the template in use with the new and updated version, the customized content is been deleted. Is is not able to update just the template, and keep the customized content inside the template.
Is there a workaround for this?
