Major update, awesome. /s
As someone who manages a network of 250+ WordPress websites - these PHP updates are killing me! As soon as I'm done helping clients upgrade/fix their incompatible themes/plugins and custom code, a new version is out! Even with great tools, the process for about 10% of my network is a nightmare.
While I appreciate the work, it's not very satisfying and for many clients very frustrating to pay for something they know nothing about, just to "keep the lights on".
The plugin/theme developers usually develop with older versions of PHP in mind, lot's of plugins still work even with 5.x versions...
For my WP sites I just stick with "two major versions behind" workflow and I don't encounter many problems.
Am I doing it wrong?
A lot of cPanel or similar hosts are also retiring old versions as they hit EOL [1][2][3][4][5] (those all support 7.4 still but most have indicated that will be dropped next year as well). This has made hosting transfers more and more difficult if you don't want to go through the process of upgrading.
The process of upgrading Wordpress sites isn't so bad (generally there's no work, honestly). But not all CMSs are that simple and it can get more laborious when you want to upgrade a Laravel or Symfony site, especially if you've skipped a few versions.
Of course, at the end of the day, it's up to the client to provide budget for these things and if they don't/can't, you just have to push back on their other requests until they do.
