Move Nagios XI from 32-bit RHEL6 to 64-bit RHEL7

[ted.boward]

Hello all,

My goal is to upgrade my old NagiosXI server from RHEL6 32 bit to RHEL7 64 bit. Without losing historical performance data, if possible.

Is this even possible?

Old System:
Red Hat Enterprise Linux Server release 6.10 (Santiago) 32-bit (virtual machine on VMWare)
Nagios XI 5.5.8
Nagios Core 4.4.2

From this article:
https://assets.nagios.com/downloads/nag ... Server.pdf

I found this command to indicate which database Nagiosxi is using:
awk '/"nagiosxi" => array\(/{getline;print}' /usr/local/nagiosxi/html/config.inc.php

Output:
"dbtype" => 'pgsql'

postgresql versions:

postgresql-server-8.4.20-8.el6_9.i686
postgresql-libs-8.4.20-8.el6_9.i686
postgresql-8.4.20-8.el6_9.i686

Thoughts?

Thank you!

You can but you want to read through this document completely, paying specific attention to the details on page 13

Preferably you would upgrade to the latest before performing the the transition to the new server.
