Deploy Next.js Website Alongside Existing Odoo Instance (Same Server)

We have a website built and ready to deploy (Next.js/React, Node-based). It needs to go live on our main domain. Current server setup: Linux server (Ubuntu) with Nginx already configured An existing Odoo instance running on this server, linked to our domain Domain currently points to Odoo What we need: Deploy our Next.js app to this server so that the main domain shows the new website Move the existing Odoo instance to a subdomain (or another accessible path) so it remains fully functional and unaffected Configure Nginx routing so both the new site and Odoo work correctly side-by-side Set up a process manager (PM2 or similar) to keep the Node app running persistently Confirm SSL/HTTPS works correctly for both the main domain and the Odoo subdomain Brief documentation on the final setup (what was changed, how to restart/update) Requirements: Experience with Nginx reverse proxy configuration and multi-app server setups Experience deploying Next.js/Node apps with PM2 Familiarity with Odoo server setups is a plus (to avoid any disruption) Comfortable with Let's Encrypt/Certbot for SSL Deliverables: Live Next.js site on the main domain Odoo instance still fully functional at a new subdomain Working HTTPS on both Short summary of what was configured To apply, please answer: Have you configured Nginx to run multiple applications (e.g., a Node app + another service like Odoo) on the same server before? What's your approach to avoiding downtime on the existing service while making these changes?
