Is it possible to change the location of the EZDrummer MIDI folder without re-installing?

Is it possible to change the folder where EZDrummer,  Toontrack Solo, and EZPlayer Pro look for their grooves with out re-installing any of these programs?
I seem to remember reading a post that indicated that this was a good idea since upgrading one of these products might overwrite any custom grooves you might have created in EZPlayer Pro.
Is that true?

Thanks!
