You don't need addnode can leave it blank had 12 connections. Also you don't necessarily have to send the coins to another adress, all you have to do is backup/extract the privatekey(s) of your Netcoin adress(es) (which i advise you to always do anyway and backup the wallet.dat aswell just to be safe).
Backing up the privatekey you can do via the console help->debugscreen. For extracting the privatekey the wallet needs to be completely unlocked if your wallet is encrypted (NOT encrypted can skip this) so type in console:

lockwallet
walletpassphrase 600

Now that the wallet is unlocked you can extract the privatekey by typing in the console:

dumpprivkey

!!! You need to do this for every single adress you want backed up and keep it safe because if someone got a hold of your privatekey they can steal your coins!!!!

Importing the privatekey into the new wallet you can read in this thread previous page or on http://forum.netcoinfoundation.org/thread/814/guide-import-paper-wallet-private

Make sure you always have the wallet from a official source so or the Netcoin github https://github.com/netcoinfoundation/netcoin or the infosite http://netcoinfoundation.org/!!!
