Severity: 3Workaround is possible

When upgrading project with particle system prefab from 5.5.x to 5.6.x, editing the particle system in 5.6.x throws Unsupported type MultiModeParameter error.

To reproduce:
1.Create new project using Unity 5.5.0f3
2.Create particle system in the hierarchy
3.Make it a prefab
4.Edit particle system settings from the hierarchy(do not press apply)
5.Open the project in Unity 5.6.x
6.Edit particle system in the hierarchy

Expected result: editing with no errors
Actual result: console throws Unsupported type MultiModeParameter error

Reproduced on: 5.6.1f1 5.6.1p1 2017.1.0b5

Notes:
Using text difference program you can see that prefabs created in 5.5.x and 5.6.x has opposite curve values, these values are opposite in all settings.
This is not a regression as the bug happens when upgrading from 5.5.x to 5.6.x.
Tested this on Win 10 and MAC OSX 10.

    confirm: Unity 5.6.1
    when editing particle system I get this error and particles stop simulating (need to press simulate again).

    I can confirm this is an issue, it seems to affect all the particle systems in a scene if the scene was serialized under Unity 5.5. Is there a known fix or workaround to this issue?

    Unity 5.6 doesn't read the settings from particle systems made in Unity 5.5 correctly, which means that editing a scene in Unity 5.6 and saving it can result in loss of data. The issue is more serious than just getting an error message when editing the particle system.
