I’m currently running Odoo 18 Enterprise on my own server and am ready to move up to Odoo 19. Because there are no custom modules or third-party integrations in the existing instance, I’m looking for a straightforward, fresh installation rather than an in-place upgrade. Your task is to: • Prepare the self-hosted environment (Ubuntu 22.04 LTS) with all required dependencies, reverse-proxy/SSL, and security hardening. • Install Odoo 19 Enterprise cleanly, activate the standard enterprise apps that ship with the platform, and confirm they all start without errors. • Import or point me to the built-in tools for moving core data from 18 to 19 (no custom code means the standard migration path should suffice). • Document every step, including commands, paths, and any configuration changes, so I can reproduce or troubleshoot later. • Provide a brief post-installation check-list (backup plan, service restart commands, log locations). No code refactoring or connector work is required; this is a clean setup and basic data migration only. If you’ve done similar, let me know roughly how long you’ll need and what access you’ll require.
