Hi
It is for the vendor best interest inform the replacement model but sometimes they just discontinue the model without a replament product.

Product migration options
There is no replacement available for the Cisco Small Business RV340 and RV345 Series at this time.
Service prices for Cisco products are subject to change after the product End-of-Sale date.
The Cisco Takeback and Recycle program helps businesses properly dispose of surplus products that have reached their end of useful life. The program is open to all business users of Cisco equipment and its associated brands and subsidiaries. For more information, go to: https://www.cisco.com/web/about/ac227/ac228/ac231/about_cisco_takeback_recycling.html."
What I suggest, on this case, it do an assessment on your network needs and find another model.
