Using Bitcoin Core wallet to sign tx offline

[yan33]

Hi,
I am using a Bitcoin Core wallet. I would like to migrate to a scheme where I can sign a tx offline on some setup and then use the online wallet to send it.
Of course I know there are wallets that allow this, and I don't mind using them, but I would very much prefer that the wallet file itself remain the one I'm using in core.
Is there a way to do this?
Thanks!

You can already do it using signrawtransaction. If you're wondering how they should look like, check this page. Or just enter either code in the console (Help > Debug window > Console).

Thanks! Now I remember I saw this command mentioned around, just didn't connect the dots.
It led me thinking of another question: If I want to generate a new change address, can that address be imported to a wallet running in pruned mode? (Or do I need to sync from scratch).

When you are pruned, you cannot import any private keys or addresses.

Okay, thanks a bunch!

Its also defeats the purpose if you move a wallet that was online to an offline system. The idea behind offline wallets is that they have never been online.
