Should I also rebuild my data container when upgrading

[Luca_Prete]

@sam thanks for the guidance.

Quicik question: we’re using the version with two separate containers.

We’ve just upgraded discourse to the latest version through the UI. Now we see the message that suggests to do git pull and rebuild.

When using launcher, should we also rebuild the data container or just the web_only?

Thanks

In this specific time I highly recommend upgrading the data container as well.

We just completed a major postgres upgrade you want to pick that up.

We of course always backup data first…anyway, should we expect any data loss during the upgrade?
Also, is there any suggested order to do the upgrade?

See:

PostgreSQL 12 update

WARNING! If your database is very large, you will need a lot of extra disk space (2x database size) and should be very careful with this upgrade! We just landed the long waited PostgreSQL major version upgrade. Any site admins rebuilding Discourse from the command line will be upgraded to PostgreSQL 12 from the old PostgreSQL 10. We are running this new version for a while on Meta, and everything is working fine. PostgreSQL 12 brings lots of improvements that will be automatical…
