Agent Upgrade Error
-------------------

Unable to determine the agent version.

Environment

Upgrade from Agent version R11.3 to R24.0 

OS: HP-UX B.11.31

Cause

As R11.3 is very old version, it's failing to determine the correct version, service pack level, and build number.

Resolution

To resolve this and allow the upgrade to proceed, follow the below steps:
1. Rename current cybAgent.bin under Agent installation path to cybAgent.bin.org

2. Create a file named cybAgent.bin with the following content:
======
echo CA Workload Automation Agent
echo "   for LINUX (Intel) 64-bit"
echo "Version R11.3, Service Pack 1, Maintenance Level 0, Build 353"

echo "Enabled plug-in(s):"
echo "- runner"
======

3. Grant execute permission (chmod 755) to the new cybAgent.bin file  

4. Once the above steps are completed, proceed with the upgrade.
