Hi yamr1,
Welcome to the PSR Tutorial Forum!
Installing new Expansion content will delete all previously installed Expansion content. Only if you have the original installation files (.ppf or .cpf) of the previously installed Expansion Packs you can reinstall them via the Expansion Manager (YEM) with the new Packs. (Installed Expansion Packs/Voices CANNOT be "extracted" from the keyboard.)
Best regards,
Chris
