Well, I'm not sure about that, as the migration worked just fine for me back then... Please ensure that you don't enter your wallet passphrase before the daemon initializes, check whether rpcwallet.exe is running in the background after about 5 minutes, and inform me whether my software requests you to enter a password on startup. If these are not the symptoms, then try re-indexing your wallet file by deleting the '.bin', and keeping the '.bin.keys'. This can take up to 30 minutes, and after that, it automatically saves in 6 minutes.
No password request shows up, GUI says initializing for the wallet. rpcwallet.exe never starts. I deleted the wallet.bin, but after half an hour, still nothing happened.
There is not much CPU activity to be seen, moneroclient.net.exe is idling at 1-2% and bitmonerod.exe does nothing.
