I saw the guide for upgrading Ubuntu 14.04 Trusty to 16.04 Xenial at https://www.virtualmin.com/documentation/system/upgrades-and-migrations. There is no guide for upgrading 16.04 to 18.04 or even 14.04 to 18.04. Since I run a Ubuntu 14.04 server I think it is time to upgrade to one of the newer LTS Ubuntu's. Has anyone experience in this? What would be your advice?
Thanks a lot!
BTW: Newer PHP versions are of no concern here.
