OPNsense updates

[pes]

I need some advice on OPNsense updates.
I plan to use OPNsense as a replacement for a real production router.
I hesitate to apply updates due to the risk of bugs that could affect OPNsense functionality.
What is the best strategy for applying updates to a production OPNsense router?

Some people find the update frequency enjoyable and those don't have much issues if at all.

Others don't like it but then simply don't update unless you have real world security concerns. You can really get away with only 2 updates per year to keep track of major updates at least.

Some forget to update at all. From a technical perspective that seems to work fine too if it fulfils your requirements.


Cheers,

• If virtualizing OPNSense, you can also make snapshots, for easy rollbacks
• Use a HA setup if budget allows it

To be honest I have 15 OPNsense VM's in production (6 /6 in HA, 3 single)with zero update issues in 2 years.

Have an additional test environment.  With open source software that can be set up pretty cheap.

Use a ZFS install and boot environments, so you can roll back if necessary:

I can confirm this for another 19 production setups, only minor upgrade issues, none of them a real show stopper.
You might also consider to use the business edition

with an upgrade path lagging behind the community edition

This hasn't been mentioned but at the very least you should take a backup of your settings and a downloaded DVD of the latest installation media before you do an update - if it all goes haywire you can always get back to the last state of your firewall. All the other replies have great suggestions that you should also consider.
