1. Introduction:
This article discusses how to upgrade Access Manager to the newer version. You must take a backup of the existing configurations before upgrading Access Manager components. For the current scenario we are considering the upgrade of NetIQ Access Manager from 4.4 SP4 to 4.5.
2. Abbreviations:
3. Pre-requisites:
a. NAM version 4.4 SP4 (Or other supported version for upgrading to 4.5.
For checking the NAM versions refer this link
b. Ansible version 2.7 or above. (For more info refer: https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html).
For checking the current Ansible version, run the following command in the terminal of the host machines:
ansible --version
Fig 1: Checking the Ansible version.
c. For this scenario, we are considering Linux based client and hosts with python version 2.7.10 or above installed on them.
d. Download the auto-upgrade.zip and extract it into the /etc/ansible (Warning: If the auto-upgrade.zip is directly extracted into the /etc/ansible folder It will overwrite the existing file in that folder.)
e. For the current scenario, we are considering setup with two Admin Consoles (AC), two Identity Servers (IDP) and two Access Gateways (AG), all running on individual Linux based systems.
f. Enter the IP Addresses of the AC, IDP and AG in the Hosts file as follows.
Fig 2: Syntax of the HOSTS file.
Fig 3: Example of entries in the HOSTS file.
g. Customized files to be mentioned in the following roles:
As shown in Fig 4.

h. The credentials for the Admin Console are Assumed to be
Username: admin
Password: novell
If using other credentials, make the changes in the following roles:
Fig 5: The underlined text shows the location of the build on the web server and the credentials.
i. We are downloading the installer from our local servers, if using some other location for downloading the build, then specify that specific location in the files mentioned in prerequisites h, as shown in Fig 5.
j. All the hosts should be accessible through the client machine using SSH.
4. Data Flow Diagram:
Fig 6: Dataflow for the upgrade
Description for the Steps of the data flow :
For verifying if, the upgrade was successful, we are comparing the rpm versions of the installed components and the rpm files in the installer, assuming that the installer is extracted in the folder /installer/NAM/
NOTE: This is just for verifying if the upgrade was successful, thus if not required it can be skipped.
Before upgrading the setup, we are coping the following files to a separate folder (/backup).
The files included are:
IDP -
1. /opt/novell/nam/idp/conf/tomcat.conf
AG-
1. /opt/novell/nam/mag/conf/tomcat.conf
NOTE: For including any other files for backup refer Prerequisite g.
5. Steps to run the Automation :
ansible-playbook main.yml -e “build_version=4.5”
And wait for the process to complete.
