I guess the question is .... can you switch to lnbits while preserving existing wallets? I have 3 made via LNDhub

You can run both at the aame time. If they're someone else's wallets you could always credit them in a newer wallet with an admin topup. After all the lnbits or lndhub wallets are just a database entry. A spendable amount from the nodes wallet, so to speak.
