upgrade from 25.7.11_9 and ISC

[jmcgee]

I am still using the default from 5 years ago, ISC.  Anything I should be aware of before upgrading to 26.1.

There are no special considerations I have seen mentioned, use of ISC or Kea or DNSmasq being essentially independent from the upgrade. ISC changes to being a plugin but still transitions as expected, or so I read because I had switched to Kea prior. Use snapshots and upgrade stuff in the order that pleases you. If you are not already using ZFS then consider seriously a reinstallation to employ it, before other work.

I had bought a second machine to operate as backup, it has two nvme drive.  I may get it up and running first.  Switch to that one, see if I can install second drive into first one.

Upgrading? No. Reinstalling to import a config? Make sure to install the ISC plugin before rebooting the thing.

thanks, I got no upgrade on existing machine.
You are saying if I
#1 reinstall opnsense on that existing machine, without snapshots,
#2 use backup to restore config,
#3 install ISC plug in,
#4 on reboot it will move settings from integrated ISC into plugin?
is that the correct order?

Kind of, yes, settings stay in place, but since the new default install does not have ISC-DHCP installing the plugin is required if you want to use it (which sounds logical).

If you can do an upgrade instead of a reinstall.  The only point to reinstall is when wanting to move from UFS to ZFS.

The upgrade is fire and forget (not counting upgrade related issues with disk, file system or package manager misbehaving which can obviously always happen but are not the norm).

OK, so I need baby steps.
Backup config.
Upgrade
Install ISC plugin?
Reboot?

And I am fine to wait for later upgrade if that will somehow ease process.

If you upgrade NOW to 26.1.1 you should be able to do it error free since they have fixed a lot of upgrading issues like the ISC-DHCP plug-in related ones for example.

26.1.0 had some upgrade issues, but 26.1.1 should not have any.

[franco]

There were no upgrading issues related to ISC-DHCP plugin that needed to be fixed. There is, however, a long standing bug in the FreeBSD package manager that can stop at any point in time due to a race condition which will definitely hit the user regarding the final installation of the ISC plugin since it is the last operation in the upgrade, but this is is neither predictable nor prevalent.

26.1.1 will be reachable from 25.7.11 tomorrow after a few more tests.
