This one is entirely on us, we wrote the custom code, which makes us responsible for maintaining it.

The upgrade status module gives us a nice report of each custom project and what changes it thinks are required to bring the code up to date to work with Drupal 10.

We really don't have a lot of custom module code, and the code that we do have is very simple, standard Drupal 8/9/10 stuff, so there are a couple of calls to taxonomy_term_load_multiple_by_name to remove, and an accessCheck to add to an entity query, but other than that our custom...

We're continuing our series on upgrading this very website to Drupal 10...but our first proper bit of work to upgrade this site is essentially nothing to do with Drupal 10!

We built this site in the early days of Drupal 8 and Drupal core didn't really handle 'media' any differently to Drupal 7, but we wanted to try out some new modules that included having a library and drag&drop upload. However, these modules are an additional thing that we need to upgrade and have been pain in that sometimes the buttons don't appear, or they're buggy in other ways. Anyway...

Let's define the scope and goals of our project to upgrade this very website to Drupal 10.

Essentially, that's it: we want to upgrade this website to Drupal 10 so that we can benefit from security releases etc.
At the moment we want to do so with the minimum of effort, so I don't want to have to be writing lots and lots of code or changing fundamentally how the site works, but I am up for simplifying things if it gets us to a point where we have to maintain less code.

Since Drupal 9, major version upgrades now...

On 14th December 2022 Drupal 10 was released. We can't say we immediately set about the task of upgrading all our Drupal 9 sites, but we did start thinking and planning to move all our sites in 2023.

I thought it might be fun to take a look at how we do an upgrade and specifically the upgrade of this very website.

So over the next few weeks we'll be slowly getting this site ready and as up to date as possible before making the jump up to Drupal 10.

We've got a few challenges ahead, this site was originally...
