See the [multi-key operations](https://redis.io/docs/latest/develop/using-commands/multi-key-operations) page for more information.\n\n\nThis command copies the value stored at the `source` key to the `destination`\nkey.\n\nBy default, the `destination` key is created in the logical database used by the\nconnection. The `DB` option allows specifying an alternative logical database\nindex for the destination key.\n\nThe command returns zero when the `destination` key already exists. The\n`REPLACE` option removes the `destination` key before copying the value to it."
