I've tried, File/Import Wallet but BitSharesX doesn't want to import the Protoshares file or wallet.dat.  The Protoshares files and Open button remain greyed out.
Should I be exporting the private keys from the old wallet and importing them into BitSharesX thru, My Accounts/User name/Keys/Import Keys from Wallet?
The answer is YES.  This area of the wallet was able to see the wallet.dat and import it successfully!  WOOP WOOP.
