Nagios Support Forum

First, is there any kind of documentation on how to upgrade php (ex 7.4 to 8.1) and still have a functioning XI system?

I'm running XI 5.9.2 on RHEL 8

Secondly, I tried it myself without really knowing what I'm doing, and everything seems almost normal, except the Database Maintenance status is Red. I see the following messages in the dbmaint.log:

SQL: DELETE FROM xi_cmp_scheduledreports_log WHERE report_run < FROM_UNIXTIME(1641860735)
PHP Fatal error: Uncaught mysqli_sql_exception: Table 'nagiosxi.xi_cmp_scheduledreports_log' doesn't exist in /app/nagios/nagiosxi/html/db/adodb/drivers/adodb-mysqli.inc.php:788

Hey @BenCowan

We currently do not have a process for manually upgrading your php version. It is recommended if you want php 8+ to migrate your distro from rhel 8 to rhel 9.

That's exactly what I did, however, if I'm not mistaken I did eventually figure it out, and migrated to 8.1 first and then moved it all to RHEL9. I did it almost 6 months ago, so I might be mistaken. I think I might have some notes somewhere.

Hey @BenCowan:

PHP 8 introduced many non backward compatible changes requiring numerous changes to XI. XI v5.9.0 was the first version to support PHP 8+, but many PHP 8 related issues have been found and fixed since v5.9.1, the version you are running. I would try upgrading your XI to the latest version, and see if that doesn't make migrating to PHP 8+ go smoother.

Yes, 5.9.1 was a prereq, as you said. I've already cleared this hurdle. Can't wait for the next one.
