user76241: I am holding for the long term and have a significant amount of bitcoin (~10) in a paper wallet (the actual private key is printed on a piece of paper). To improve security measures and possibly sell forked coins, I would like to transfer the funds to a new address (paper or hardware wallet).
I understand the technical procedure - sweep the private key into a wallet software and send to the new address. I am concerned about taking the proper security measures.
Some online resources recommend myCelium, but while I am cautious I do not trust my Android devices to be free of malware. I plan on using a PC with a Live CD Linux distribution (e.g. Ubuntu) installed on a fresh USB disk and connected behind a home router.

Are there any other security measures I can take besides running an OS with no malware and a reputable wallet software?
Are there any specific disadvantages to using Electrum for this vs. running a full node wallet such as Bitcoin QT (besides privacy)?
Does the Electrum Cold Storage feature (signing transactions on an offline machine) has any benefits for a one time transaction?


user63569: Just go ahead with Bitcoin-core. Which is much more secure than the others.
Encrypt your wallet with some long strong password and you're good to go.
