Currently installation
Nagios XI version: 5.6.10
Release info: 3.10.0-1127.19.1.el7.x86_64 x86_64
Red Hat Enterprise Linux Server release 7.8 (Maipo)
Gnome Installed

Is the upgrade to 5.7 going to include everything needed or are there dependencies that need to be addressed first. The server does not have internet access so there is no download available. Any dependencies would have to be addressed manually.

Did you install Nagios XI 5.6.10 in an offline environment according to the instructions below?

https://repo.nagios.com/?repo=offline

If you did, you could upgrade to Nagios XI 5.7.3 without any issues.

Offline server must still have access to RHEL Base & Optional Channel Repo (actual or clone) for installation/upgrade

RHEL 7 Optional Channel Packages

dejavu-lgc-sans-fonts.noarch
dejavu-lgc-sans-mono-fonts.noarch
graphviz-gd.x86_64
perl-Crypt-DES.x86_64
perl-Parse-RecDescent.noarch
php-mbstring.x86_64
php-snmp.x86_64

If you however did an online install, then you brought your server offline, you wouldn't be able to upgrade this way.
