How to old wallet on extern Harddisk on new Wallet?

Hello :slight_smile:
I need some help please. Some years ago i buyed LTC and stored them on Harddisk offline netbook wallet Core.
The old Netbook broke, but i have its harddisk here. I now want to send these LTC to a new wallet.
Therefore i have downloaded Core and eletrulum-LTC. Updating Core needs over 30 hours. Is there a faster way? Importing the wallet.dat to Elecrum-LTC?
I also would use a online wallet, but registration is difficult, seems they take no new members, coinbase and anycoindirect.eu .

Thank you in advance!

Just paste your wallet.dat at the appdata and everything just will like an oldtime

But updating the Blockchain seems necessary :slightly_frowning_face:

Whatโ€™s the problem with updating?
