Debian Upgrade Coming Up (Soon)

We've begun testing a Debian upgrade for our infrastructure (so far it looks like it can go well and improvements are to be made along the way). Yesterday we contacted the datacentre staff about it (there's maintenance going on at this very moment*). It was a headsup. Depending on certainty associated with the impending upgrade, we shall set a date and complete the job. Being an SSG, it seems possible that site downtime will be minimal (as long as the files are in the right place and Apache is running/restarted OK, the visitors won't spot problems).
Today I checked my laptop (that I am typing this into) and it says its uptime will eclipse 900 days around the end of next month or start of June:
roy@bubi:~$ uptime 07:00:02 up 862 days, 22:12, 3 users, load average: 7.02, 7.02, 7.00
Last rebooted in 2023. It's not Web-facing and isn't used to access the Web. █
