Hi Ken, Does this app use 4D Write? If it does, and if you ever think this app will move beyond v17, you gotta think about 64 bit, if you haven’t already.
Also, Chuck mentioned getting pictures converted, but there’s more to 64bit compatibility. Would be good to run a 64 bit compatibility audit on it. Furthermore, if you do go beyond v17 and want to use Project Mode (which I think is inevitable given that there are features which only work when using Project Mode; that will only increase over time) your structure also needs to be Project Mode compatible. You can run Export Structure File in v17r4 or greater to find out what Project Mode incompatibilities need to be addressed. This blog post <https://blog.4d.com/convert-an-existing-database-into-a-project/> includes a good overview of compatibility issues. If the structure uses Highlight Buttons, those will need to be manually converted to 3D Buttons.
