New wallets created with Bitcoin Core v 23.0 RC3 have by default descriptors=true and taproot descriptor is generated.

Using a wallet created with descriptors=true with the precedent version 22.0 does not allow me to create receiving Bech32taproot address (which is normal, since by that time "desc": "tr was not present).

I've tried to upgrade wallet with the command "upgradewallet" but it is already at latest version: { "wallet_name": "wallet_22.0", "previous_version": 169900, "current_version": 169900, "result": "Already at latest version. Wallet version unchanged." }

I think it would be great a way to upgrade/add taproot descriptors to the wallet instead of having to create a new one.

We're working on it. #23417 is required, then a followup will be opened that actually adds the ability to add the descriptor.

Thanks for your answer @achow101
