Error in FMODMigrationUtil.cs (FMOD 2.00)

I uninstalled my old fmod, and installed fmod 2.00. I also removed old fmod unity package files from my unity project, and imported the fmod 2.00 package. Now I get the following error in unity.

Assets/Editor/FMODMigrationUtil.cs(136,50): error CS0246: The type or namespace name `FMOD_StudioEventEmitter’ could not be found. Are you missing an assembly reference?

To be clear, FMODMigrationUtil.cs is something from the fmod package. Should I try adding a using statement to that code? What using statement does it need at the top of the file? The FMOD_StudioEventEmitter type doesn’t seem to be inside the FMOD, FMOD.Studio, or FMODUnity namespaces.

The FMODMigrationUtil.cs was removed in FMOD 2.0.
You may have missed it when removing the old integration as it was separate to the rest of the files:
