Version upgrade 2.7 to 5

[sgoffar]

Can you please send us the steps to upgrade Nagios Xi from2014 2.7 to 5.

What are the risk,mitigation plan and back out plan of this migration. Also advantage of up-gradation and cost.

Just to get some clarification, are you using Nagios XI or Nagios Core? This was posted in the XI Forum, but Core would be the program that had a version 2.7. A screenshot showing your version would help as well.

I am using Nagios Xi. Below is the details:

Version:Nagios XI 2014R2.7

Got it, that helps clarify what you're running. Now, back to your original question -

What are the risk,mitigation plan and back out plan of this migration. Also advantage of up-gradation and cost.

No risk really. As always, take a snapshot of the machine before you upgrade and that can serve as your plan if things do not succeed. XI5 is a newer, major release, with quite a bit new functionality. You can look at the entire change log here - https://assets.nagios.com/downloads/nag ... NGES-5.TXT

For questions about the cost, please email [email protected] with your questions.

Is the below task as mentioned on release note is enough. We don't needs to do anything on DB side?

SL No Task Details
1 Take Backup of Nagios Xi
2 Take Snapshot backup of Nagios Appliance
3 Download Upgrade package to Nagios server
4 Unzip and Run the Upgrade Script
5 Check The Upgrade version from Console

[rkennedy]

One thing to check, were you previously using postgres? Please run this command and share the output -

Code: Select all

grep -R 'dbtype' /usr/local/nagiosxi/html/config.inc.php

When you run the backup, it will backup your databases, but if you're going from SQL -> Postgres for Nagios XI it will not work for the nagiosxi database - https://assets.nagios.com/downloads/nag ... ios-XI.pdf

The backup script will save a copy of the following components of Nagios XI:
•
Nagios Core files (
/usr/local/nagios
)
•
Nagios XI files (
/usr/local/nagiosxi
)
•
NagiosQL files (
/var/www/html/nagiosql
and
/etc/nagiosql
)
•
Select Apache config files (in
/etc/httpd/conf.d
)
•
Select logrotate config files (in
/etc/logrotate.d
)
•
Select MySQL databases (
nagios
and
nagiosql
)
•
Select PostgresQL databases (
nagiosxi
)

Please find below details:

[root@dfwlxngxi01 ~]# grep -R 'dbtype' /usr/local/nagiosxi/html/config.inc.php
$cfg['dbtype'] = ''; // this setting is no longer used - use settings below
"dbtype" => 'pgsql',
"dbtype" => 'mysql',
"dbtype" => 'mysql',
//require_once(dirname(__FILE__).'/db/'.$cfg['dbtype'].'.inc.php');

Also We don't needs to do anything on existing agents for Monitoring servers right?

[rkennedy]

"dbtype" => 'pgsql',

This will cause issues, as previous versions used postgres, but the current version will use mysql. When you deploy out a new machine on XI5 already, it's going to be expecting the mysql, but your backup will have the postgres data

If you want to start fresh, and keep all of the information from the nagiosxi database (user configurations and such), then you'll want to deploy a fresh 2014 machine, clean upgrade from this, and then do the backup / restore process.

I am not clear on last point. As per my understanding both the mysql and pgsql are present in current version.

And pgsql is used to store nagiosxi data only. For current version u mean there is no pgsql db concept.

"dbtype" => 'mysql',

pgsql is not on fresh installs of new versions. On upgrades it gets pushed along. Does that clarify the point for you?
