With the release of NAV 2018, first thing that comes to mind is how much objects are changed from previous version. To check this I have performed small comparison straight forward on NAV 2017 W1 and NAV 2018 W1 database objects.
I have used power shell commands for quick comparison.
Here we go->
In this example, the DEMOUPGRADE folder contains five folders: ORIGINAL, MODIFIED, TARGET, DELTA, and RESULT. The DELTA and RESULT folders are empty. The ORIGINAL, MODIFIED, and TARGET folders contains one or more text files that contain application objects. You can now run the cmdlet. In my case Original = NAV 2017 W1 and Modified = NAV 2018 W1objects.
Compare-NAVApplicationObject -OriginalPath .\ORIGINAL -ModifiedPath .\MODIFIED -DeltaPath .\DELTA
This generates a number of DELTA files that describe the difference between ORIGINAL and MODIFIED. You can open the DELTA files in text editors such as Notepad.
The following example illustrates how a DELTA file identifies the difference between ORIGINAL and MODIFIED.
You can identify those differences in DELTA folder.
However on top level review I found there is major change in properties, changes in field size and new codes additions.
Out of which 1014 objects have minor changes like insert, modify or deletion of simple properties or one line code etc.
Virtual Table Changes after 2017:
New Additions in 2018
Deletion from 2017 in 2018
List of Virtual Tables in NAV 2018, are new additions and rest is common from 2017
List of New Objects in NAV 2018
I will come with more details as I proceed on same.
