i created my wallet in 2011 and i still use it today. it is still in Non-HD format. turning an older wallet into a HD wallet is a manual process.
So how do you manage your wallet, do you have a 2 laptop setup with a watch-only wallet? Also, what will you do once Core 30 deprecates your wallet? Im using Knots 28 so I don't know what they will do in this regard.
on core 27.1 here
i just have a bog standard wallet created in mid 2011 and i just did in place upgrades from there.
when the original HD format was introduced i elected to keep my old wallet instead of creating a new
one as i had mining payout addys in it and exchange whitelisted addys etc in it and, as im lazy af, i just kept the old format and made sure i always backed up wallet.dat to make sure any new keys generated would my in my backup set.
now with core supporting multiple wallets i can make a new HD format and use it
in parallel BUT im pissed that legacy wallets wont be supported
... from 30 on?? wtf satoshi said never lose control of your private keys... so i guess ill run a final pre 30 version and run it in parallel on a dedicated machine.
