The IC Express is a great version for those seeking to start out with basic integrations who may wish to expand in the future. However, there are some very basic functionalities missing and that is concerning. In particular, the lost of the "Advanced Options" in an update task:
> Allow Null Updates to Target
> Target Batch Size
> Create the Success File
I consider these basic integration functionality and would recommend including them in the Express Tier 1 version. The inability to update fields to Null is particularly limiting.
