Sceneries for v4 used in v5

[romair]

Hello Experts

Since the MSFS came to the market many scenery developer focus to the new MSFS.
At this time they to not much more modifications on scenery addons for the use with P3Dv5.
I am operating v4.5 and today mainly v5 (very satisfayed still)
A lot of sceneries aren not yet modified for the v5 version.

What are the main differences between an addon scenery made for version 4 and possible use in v5.
What have to be modified (airport altitude). Can it be daone by an normal user with some knowledges with ADE.
In my case PBR lights are not impoertant.

regards Roger
