Steps to build with GeneXus 17 a KB of GeneXus 16

There is no Knowledge Base conversion from GeneXus 16 to GeneXus 17. GeneXus 17, technically speaking, is just an upgrade of GeneXus 16 Upgrade 11 and so is very easy to adopt.

To open a Knowledge Base (KB) that is already on GeneXus 16 with GeneXus 17 follow these steps:

1.A) If your KB is not connected to a GeneXus Server: Open it with GeneXus 17.
Note: Since no conversion happens, you will be able to open it with Genexus 16 if you need to return back

1.B) If your KB is connected to a GeneXus Server

1.B.1) If you decide to install GeneXus Server on another instance

1.B.2) If you update to GeneXus 17 your GeneXus Server 16 instance

  • Update the instance to GeneXus Server 17. Do it following the steps described at GeneXus Server Setup (Section "Update an existing GeneXus Server Instance")
  • Open your KB with GeneXus 17

2) Build All/Rebuild All (*)

If your KB uses GeneXus Access Manager (GAM) or BPM this process may update the associated database schemas. See below for more information.

(*) If you generate for Android or iOS,

  • delete the <Environment Directory>\mobile\iOS folder before doing a Rebuild with GeneXus 17.

To compile iOS Smart Devices Apps,

  • Delete the content (for each user of the mac that is about to compile code)
  • Delete the folder “build” that is in

3) Check out Navigation changes using the Navigation Comparer. Note that navigations may change given several navigation improvements. Check out 'Navigation Improvements' section at this page.

4) Test it

5) If the KB is connected to GeneXus Server, commit changes.
