migratewallet (26.0.0 RPC)

migratewallet ( "wallet_name" "passphrase" )

EXPERIMENTAL warning: This call may not work as expected and may be changed in future releases

Migrate the wallet to a descriptor wallet.
A new wallet backup will need to be made.

The migration process will create a backup of the wallet before migrating. This backup
file will be named <wallet name>-<timestamp>.legacy.bak and can be found in the directory
for this wallet. In the event of an incorrect migration, the backup can be restored using restorewallet.
Encrypted wallets must have the passphrase provided as an argument to this call.

2. passphrase     (string, optional) The wallet passphrase
