Thanks for your help.

Yes. Laptop 1 was once used to receive my bitcoin a couple of years ago. But since then has stayed offline. Has v21

Laptop 2 is connected to the internet but only for the purpose now of broadcasting my spending tx.
Will have V23 or can just keep v21.

I was just confused how to sign the offline tx on the airgapped laptop 1.

I was told that since I'm not technical and seem unable to understand the descriptor process or making a manual raw tx.

Then my only other way was to simply send (signed, where I type my wallet passphrase in) as normal with core unsynced on latop1 then close v21 down.

Copy then entire bitcoin folder over to laptop 2 which is connected to the internet and when it syncs up it will broadcast the tx
So although my keys will be on laptop 2 which is connected to the internet they are actually encrypted by my password that I dont need to enter because the tx was signed on the air gapped laptop 1 unsynced wallet.

The only problem with this easier way is that now the airgapped laptop can not sign any further tx in the future  until I update its blockchain to later date that the spend takes place. So in theory I will need to later copy the synced appdata file back from the internet connected laptop to the airgapped laptop.

I just wanted to check there are no big issues with this way.

I was thinking about sweeping to an electrum wallet and using the watch only psbt guide.
But if I can do this with core just have to copy over the appdata bitcoin folder and no programming with the bitcoin core console instructions. Then I'll stick with bitcoin core.

I'll work out the safest way to get the updated bitcoin folder back over to the airgapped machine in a few years when I may need to spend the last 0.005. I suppose this is the most risky part.

Thanks for the help. I see what you mean laptop 1 isnt a real cold wallet because it has been on the internet to receive the btc a couple of years ago.

If you think it's going to work I'll give it a try.
