The anchor contract expires! A written agreement needs to be issued 1 month before the expiration of the contract terms, otherwise it will be renewed automatically. Is this necessary?

This is not recommended. If there is an agreement in the contract, it is recommended to indicate in writing that the contract will not be renewed. Even after a month's deadline, you can terminate the contract. But they must be notified in writing to cancel it, so that it can have the effect of notification, not just making a phone call or something. Your contract is certainly legally binding, but it does not affect your initiative to terminate the contract now.
