I have stored my DNR on a very old wallet like 6 months old.
Will i lose my DNR when i dont update this wallet?
No, you wont lose your DNR.
But before upgrading to a new version of wallet first backup your wallet.dat just in case.
Ok thanks.
Got a few more questions.
How do i update a wallet?
Just download and send my coins to the new wallet?
No,
Just download new wallet, unpack and start.
After that it will re-index blocks and sync if there is something to sync to be up to date.
You should see you coins after that, don't need to create any new address or anything for that matter.
Backup of wallet.dat is just precaution if something goes wrong in the process.
