Nextcloud version: 19.0.2
Ubuntu headless server: 18.04 LTS
PHP: 7.4.9 (cli)
Apache: 2.4.29 (Ubuntu)
Nextcloud is up and running without errors and works great. I want to upgrade from Ubuntu 18.04 LTS to 20.04 LTS. I am a relative newbie to Linux and have been going through this forum, and other online resources to setup Nextcloud and play around with it.
The question I have is what preparation work do I need to do before I upgrade the OS? I know there are some very knowledgeable and experienced people on this forum so are there any tips or pointers anyone can give to try and avoid common pitfalls (aside from backing up) before upgrading? This would be helpful for us less experienced people.
Thank you in advance for any tips.
