Thanks for letting me know Matthias!
I figured it wasn't possible between different interfaces.

The paths are described in the manual. It's all there and can esasily be copied. Of course it would have been more wise to first save everything as Workspace file and just copy that one to the new machine.

I tried, so to give an answer to myself:
Yes, it is possible, just renaming the xml or copying all the text is not sufficient though, as the interface's name and serial number are mentioned several times in the xml file.
Opening that with a text editor and searching and replacing all those names with the new interface's name and serial number did the trick.
Everything is there from eq and dynamic settings to snapshots, just fader and mute groups were lost, but these were quick to restore.

I tried that, was not working (maybe since the UFX II is not then same model as the UFX+?)

Hello, I have Babyface Pro FS. As I suppose it is possible to save Totalmix workspace and open it from another computer and from another Babyface Pro FS unit, am I right?

Is there any other RME model (different than BF Pro FS) to which I can import workspace from BF Pro FS?

If not, is it at least possible to export FX pressets (EQ, reverb, delay) to different RME units (those with FX functionality)?

Thank you for response.
By saying „works independent of the device” you mean, that I can export EQ/rev/delay presset from BF Pro FS and import it to e.g. Fireface UXC II (and any other model with FX)?

What about workspace? Can I open it from different BF Pro FS unit and is there any other RME model, from which I can open this workspace?

Edit: I am asking, because I would like to know how flexible is process of exchanging settings in RME environment. I am preparing new composition with live electronics and there is chance I will not be at its premiere, so if the performer will have RME device, I have to know how much compatible will be Totalmix settings I prepare for him in my home.
