System Information
Operating system: Windows-10-10.0.22631-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 4080 SUPER/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 552.22

Blender Version
Broken version: 4.2.0 Alpha, branch: main, commit date: 2024-04-30 20:02, hash: 02f2d73b78f4
Broken version: 4.1.1
Broken version: 4.0.2
Worked: 3.6.11

Caused by d9da86dd15

Short description of error
The versioning code that enabled View Layer -> Filter -> Denoising on old files (E.G. Files from the Blender 2.79 era) doesn't appear to be functioning properly in newer versions of Blender

Exact steps for others to reproduce the error

Download and open a old Blender file in a new version of Blender. The Barbershop scene from https://www.blender.org/download/demo-files/ seems to have this issue.
Notice that View Layer Properties -> Filter -> Denoising is disabled.
Compare this to older versions of Blender like 3.0.0 and notice it is enabled there.

Original reoprt

**Blender Version** Broken: version: 4.2.0 Alpha, branch: main, commit date: 2024-04-30 20:02, hash: `02f2d73b78f4` Worked: previous build of 4.2.0 alpha (not sure of hash as deleted the zip now)

when final render completes, no denoising happens to the combined pass. Same issue when using open image denoise with or without the new use gpu option. Also denoising doesn't happen with optix.

Tried changing between cuda and optix in the system preferences, but both have the same issue.

Viewport denoising works fine for both optix and OIDN, but it did take an excessively long time before the first sample after changing to rendered viewport mode.

The compositor denoise node works fine.

This is a fresh installation of blender with no addons installed.

Exact steps for others to reproduce the error

open barbershop
change render settings to:
hit render
render finishes fast, but no denoising happens.

Just tried a new scene, and denoising does work. Must be caused by an incompatibility with blend files created in previous versions of Blender perhaps? Although I did resave in blender 4.2 alpha, but still no joy.
