This is a very hard question to give any advice on. There are a lot of factors that could affect the decision.
Things to consider: - Complexity of the structure (# of tables, forms, methods, etc) - Are there any old style 4D extensions used? - Are there any plugins that are no longer supported? - Is the existing code readable and easy to understand? Have you tried converting it to v17 to see if it is even possible? It might convert and everything works and then again it might not. If they want the data converted as well, then you are going to have to deal with the subtables and the existing structure.
