Upgrading from 2.3.4 to 2.7.2

Hello, we are attempting to upgrade from pfsense CE 2.3.4 to 2.7.2 and are having several errors when trying to reinstall and importing the config.

Here's the two different errors:
Error 1:
[12-Mar-2024 08:58:07 America/New_York] PHP Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /etc/inc/upgrade_config.inc:5444
Stack trace:

Error 2:
[12-Mar-2024 09:46:16 America/New_York] PHP Fatal error: Uncaught Error: Call to undefined function additional_config_upgrade() in /etc/inc/config.lib.inc:535

We have about 3 firewalls that we are attempting to run this on, and it seems to be something with the importing of the config, causing a loss of connectivity until we reassign the interfaces on boot. When I go in and comment out convert_config() in /etc/rc.bootup it appears to resolve this issue for us, however I don't want this to be a issue in the future, if we need to upgrade again.

Thank You,

Are you seeing the same errors on all three configs?

The first error there looks like: [https://redmine.pfsense.org/issues/15195](link url)

Probably because there are empty <ppp> tags in the config.

@stephenw10 Yep, I that resolved the error for one of the configs. Let me try editing the configs on the other 2 firewalls.
