Hello – if you can read this, then the server upgrade worked!
I’ve wiped the previous server image (yes, I remembered to do more than one type of backup this time), and installed a freshly upgraded version of Linux. This means it’s running on Debian 12 (codenamed ‘bookworm’), and version 12 of Sympl. Sympl is a set of tools for Debian that makes managing a web server remotely a little easier, and is forked from Symbiosis which was originally developed by my hosting company Bytemark.
Going nuclear and starting from a fresh installation was for two reasons:
- The next version of WordPress, which will be 6.4, will have a minimum recommended PHP version of 8.1. This server was running version PHP 7.3, and whilst I’m sure future versions would work up to a point, it’s a good opportunity to upgrade.
- I’ve had a few issues with the previous installation. The FTP server software never seemed to work correctly, and the database (MariaDB) would lock up almost every time I posted a new blog post. Hopefully, this won’t happen anymore.
As this is a fresh WordPress installation, there may be a few things which don’t quite work yet. I’ve imported the existing blog posts and pages, and the theme is mostly the same, but I need to re-install the plugins and probably need to amend some settings. I’ll sort these issues out over the next few days.
