Unity 2017 to 2019 switch

Hi guys,

I changed over from Unity 2017 to Unity 2019 and I imported the project I've been working on and I'm getting the following two errors:

Lighting data asset LightingData is incompatible with the current Unity version. Please use Generate Lighting to rebuild the lighting data. Realtime Global Illumination cannot be used until the lighting data is rebuilt.

C:/Program Files/Unity/Hub/Editor/2019.1.0f2/Editor/Data/Resources/PackageManager/BuiltInPackages/com.unity.timeline/Editor/inspectors/ClipInspector/ClipInspector.cs(364,17): warning CS0219: The variable `editorClip' is assigned but its value is never used

And then 66 of these errors:

C:/Users/chris/Desktop/Unity/Game Templates/Tower-Defense-Tutorial-master/Tower Defense Unity Project/Library/PackageCache/com.unity.textmeshpro@2.0.0/Scripts/Runtime/TMPro_UGUI_Private.cs(2041,130): error CS1644: Feature `out variable declaration' cannot be used because it is not part of the C# 4.0 language specification

Any help appreciated, thanks.

 

Try deleting packages like TextMeshPro. It helped me
