[API update]API updating fails when trying to update from 4.7 to 5.X

Scripting

-

Priority: 3Not yet prioritized for a release

-

Severity: 0Severity not yet defined

Steps to reproduce:
1. Download and open project (link provided below).
2. "Project Upgrade Required" window appears. Click "Upgrade" button.
3. "API Update Required" window appears. Click "I Made a Backup. Go Ahead!"
4. Notice that when the Editor opens, the "Console" window outputs several error messages, for instance:

"Assets/Standard Assets/Scripts/Utility Scripts/MeshCombineUtility.cs(130,73): error CS1061: Type `UnityEngine.Mesh' does not contain a definition for `GetTriangleStrip' and no extension method `GetTriangleStrip' of type `UnityEngine.Mesh' could be found (are you missing a using directive or an assembly reference?)"

Also, it informs that:

"Some scripts have compilation errors which may prevent obsolete API usages to get updated. Obsolete API updating will continue automatically after these errors get fixed."

4. Open script named "MeshCombineUtility".
5. Change these fragments of code: "TriangleStrip" to "Triangles".
6. Go back to the Editor.
7. Notice the output of the "Console" window:

"API updating failed. Check previous console messages."
Failed to run script updater.

Expected result:
Scripts should be updated fine when importing from 4.7 to 5.X.
