MEW & ledger nano s setup

So I created a MEW account with a private key last year and transferred some ETH & ERC20 tokens in. Now I would like to boost security with a ledger nano s. Should I use my existing MEW, or create a new one to use with the ledger? Also do you recommend using the online MEW or to run it locally?
