How to extract plugin parameters for a 32-bit audiounit and paste them into a 64bit VST with the same name?

Help, Support & Bugs

I just tried to do this: Copy parameters from a non-loading 32-bit AudioUnit (TAL-Dub III) to 64-bit VST (TAL-Dub-3) - in theory the same plugin.

Got this:
“Can not copy device settings from a ‘aumf:xg70:TOGU’ to a 'TAL-Dub-3”

What should I be doing. Is there some Console / Scripting method for extracting the settings from the non-loading 32bit AU, or…?
