I’m in the process of bringing up an over year old installation of Trellis (using the steps found in this guide: http://www.chrisknightindustries.com/2015/24/11/git-subtrees-for-trellis-workflow.html) from pre-1.0 to 1.2.0 — which has since added Ubuntu 18.04 support and started defaulting to it. The initial install was running a different version of PHP(7.2) and Ubuntu 16.04 Xenial LTS.
I am wondering if re-provisioning the server with Ansible will bring up and update Ubuntu, or if I will need to spin up a separate droplet with a clean installation of 18.04 instead? Just curious about the best practices here to ensure there are no problems with the production environment. Any advice or help would be greatly appreciated.
