Proxy inbound connection to external ip

Good morning,
I currently have a server in an on-premise datacenter that responds to TCP port 12233.
So there is a very normal DNAT on the XGS firewall of the public ip 80.80.80.80:12233 towards the private server ip 192.168.1.10:12233
This service is only used by external clients with a mobile application configured to point to 80.80.80.80:12233.

I'm migrating this local server to the cloud so when the migration is complete the server will respond to 90.90.90:12233.
Since there are hundreds of clients to reconfigure to point to the new address, I wanted to find a solution that would allow us to reconfigure them gradually. I thought of using a reverse proxy like NGINX which will take the place of the old local server and redirect the calls towards 90.90.90: 12233.

I was wondering if it was possible to do this sort of reverse proxy directly from the firewall without having to set up an NGINX, perhaps with a source NAT. In your opinion is it possible?
