Just found out a post is limited to 32000 characters and my other Personal Notes is near the limit.

Most installations (including all Discourse official hosting) are betas, being on a release version is more conservative. New betas are released every few weeks. Full releases come, at most, every 6 months.

:bell: Before you switch over to the new server, review your app.yml for any optional settings such as CDN, installed plugins, and HTTPS support between the two Discourse instances. It’s easier to make sure the two instances are identical before you begin restoring the backup.

Development installs normally aren’t set up to actually send emails but use MailCatcher to simulate it. Here’s how you start it:

mailcatcher --http-ip 0.0.0.0

Installation notes for Discourse on Bash for Windows - This is old and out dated but still has useful information.

This is how we plan to upgrade next month:

  1. Pick a slow traffic time on the weekend
  2. Set DNS TTL to 5 minutes (already done in our case)
  3. Create a new VPS server.
  4. Do fresh “two container” install with ngnix reverse proxy to unix socket.
  5. Confirm all is working.
  6. Take full backup of original (PG 10) production configuration.
  7. Move backup to new VPS server.
  8. Restore new VPS server (now running PG 12) with the full backup from production PG 10 setup.
  9. Change DNS.
  10. Confirm all is well and then destroy original VPS server.

For us, this is the “lowest risk of an error” way to go with the least amount of downtime.

A nice way to see what others find important with Discourse is to view the list of topics sorted by number of views descending. (ref) What is surprising about the list is that many of the top topics at the top of the list are significant to learning how or self-host or or what others do when self-hosting.

Recommended Email Providers for Discourse (ref)

We strongly recommend using a dedicated email service. Email server setup and maintenance is very difficult even for experienced system administrators, and getting any part of the complex required email setup wrong means your email won’t be delivered, or worse, delivered erratically.

Things Discouse will probably never do:

  1. hierarchical or nested conversation threading (ref 1) (ref 2) - Discourse uses linear or flat conversation threading. Discourse topics can be split into other topics. (ref)
