I have cold storage setup in a very old computer, now that I want to move it to a little bit better one, with whole hard disk encrypted by PGP. Before I start, I want to hear from gurus here. Is this simple process, just install electrum in the new computer, enter the seed, and done? Then I can wipe the disk of old computer and throw it away?
Thanks in advance!
You can do that.
You can also use File > Save Copy to create a backup copy of your wallet.
You can also get the actual wallet.dat file from your %Appdata%/Electrum/wallets folder.
Note: I am assuming that your current Bitcoin client is also Electrum.
