Hi!
I recently set up a new marketing app in an existing environment. The process informed me that this could take up to 1 hour. The result was that it took over 3 hours and 68 solutions were installed, including base solutions and patches related to marketing. The environment was pretty much useless during this period, with SQL timeouts and generally very unresponsive.
So the question now is, will this be the same when I set this up in a live customer production environment? What is your experience when setting up Marketing for the first time? The Power Platform Build Tools and the SDK has support for async solution import. I can hardly see Microsoft using that themselves given the behavior of the instance as described earlier. Your thoughts?
