Upgrade Step 2: Prepare for the Upgrade

In this second step of the upgrade process, you complete the following two important steps:
uim901
In this second step of the upgrade process, you complete the following two important steps:
  1. Plan for the upgrade. When planning for the upgrade, you refer to the compatibilities and other important documents to ensure that your components, environment, hardware, and operating system requirements are prepared and are compliant for a successful upgrade. Then, a sizing plan is created using sizing calculators.
  2. Complete important pre-upgrade tasks. Verify custom configurations and integrations, and define a backup, recovery, and failover plan.
The following video highlights this two-part process to ensure that you are properly prepared for the upgrade.

Plan for the Upgrade
After the existing CA UIM environment is evaluated, you plan for the upgrade. Use the following documents and reference information to prepare and plan.
  1.  Unified Infrastructure Management Compatibility Matrix. This important document provides a compatibility matrix to help you identify the components that are compatible with the different versions of CA UIM.
    You should carefully read all sections of the compatibility matrix. You should pay close attention to the following highlighted sections.
    •  
      Component Support Matrix
      . Identifies new components that are supported and other components that are no longer supported.
    •  
      Supported Upgrade Paths
      . Highlights supported upgrade paths for each CA UIM component. Some component versions required that you upgrade to a previous version before upgrading to the most current version.
  2.  CA UIM Release Notes, available in the product documentation. This important document provides the latest information about new features, enhancements to existing features, and defects fixed.
    You should carefully read all sections of the CA UIM Release Notes. You should pay close attention to the following highlighted sections.
    •  
      New Features
      . Highlights the new features. New product functionality can impact the existing functionality. Review this section so you are aware of any actions that you might need to take so that your existing functionality works as expected.
    •  
      Support Updates
      . Highlights software support updates. Be aware of any software that is no longer supported.
    •  
      Updated Probes and Packages List
      . Be aware of the component version number for the probes and packages that are installed.
    •  
      Resolved Issues
      . Be aware of the issues resolved and how that can impact your upgrade.
    •  
      Known Issues
      . Be aware of known issues and how that can impact your upgrade.
  3. You should carefully read all section of the CA Business Intelligence Release Notes. You should pay close attention to the following highlighted sections.
    •  
      Installation and Upgrade Procedures
      . As of the CA UIM 8.5 release, the process that you use to upgrade your CA Business Intelligence servers differ, based on several factors in your CA UIM environment. Read this section and be aware of the correct upgrade procedures.
    •  
      CA UIM Environment Requirements
      . CA Business Intelligence requires certain components that you should be aware of for a successful upgrade.
    •  
      Hardware Requirements for CABI Server
      . Be aware of any CA Business Intelligence hardware requirements.
    •  
      New Features and New Packages
      . Be aware of the new feature and packages that can impact your upgrade.
    •  
      Resolved Issues
      . Be aware of the issues that are resolved and how that can impact your upgrade.
    •  
      Known Issues
      . Be aware of known issues and how that can impact your upgrade.
  4.  Probe-Specific Release Notes, available in the product documentation.
    For any probe that you have deployed, carefully read their Release Notes. You should pay close attention to the following highlighted sections.
    •  
      Installation Considerations
      . Be aware of any probe-specific installation considerations.
    •  
      Upgrade Considerations
      . Be aware of any probe-specific upgrade considerations.
  5.  Knowledge base (KB) articles, available on the CA Unified Infrastructure Management page of CA Support Online.
    Become knowledgeable and be aware of any upgrade-related KB articles on CA Support Online that can impact your upgrade.
  6. Identify factors affecting the capacity of each CA UIM component and size the resources to be allocated. For example, consider the following information:
    • Hubs. The capacity of the hubs depends on how they will be deployed. Determine if you need to deploy the hub as a standalone system or install it in a multi-tiered environment. In addition, there are multiple factors to consider when planning hub deployment. For example, the number of devices, scalability, the number of metrics and alarms that robots report, probe-specific requirements, and the geographic locations including DMZ telling requirements.
    • CA UIM Database. The CA UIM database stores device inventory, alarms, and QoS data. Determine if you need to perform capacity planning for the CA UIM database. If so, understand that the CA UIM database stores many statistics-based inputs. The Database Disk Space Calculator, which is part of the health check, sizes the CA UIM database and estimates the total metric load. This information can help you estimate the number of metrics that hubs, probes, and the database can handle based on your environment. The health check makes recommendations, provides the future sizing criteria, and delivers a roadmap to that future state.
  7. We recommend that you contact your CA Services representative and let them know that you are starting the upgrade process. Discuss with your representative your unique upgrade challenges and gather information and best practices that you can use for your specific environment.
Complete Important Pre-Upgrade Tasks
A backup and recovery plan is crucial when planning for the upgrade.
 
Follow these steps:
 
  1. Gather, note, and keep in a safe place the CA UIM Administrator and CA UIM Database accounts.
  2. Note any custom configurations that are made to the hub. If necessary, you can restore to the previous version in case you encounter unexpected issues or behavior.
  3. Take a snapshot of the server.
  4. Make a copy of the key directories. For example, directories for any integrated products, and the CA UIM infrastructure servers and their directories. After the hubs are upgraded, this information will help you set up the CA UIM environment that is part of the post-upgrade configuration.
  5. Note any custom scripts that were deployed.
  6. Back up the appropriate systems. For example, you previously took a snapshot of the server as part of the recovery plan. Now, back up and rename the previous CA UIM directory.
  7. Remove any custom probes in the probe archive, but leave the infrastructure probes. After the upgrade is complete, you will selectively move the customized probes back into the archive.
  8. Back up the CA UIM database.
  9. Take a backup of the existing licenses before upgrading to CA UIM 9.2.0. From CA UIM 9.2.0 onward, hub/robot- and probe-level licensing requirements have been removed. Deploy the hub, robot, and distsrv versions released with CA UIM 9.2.0 to remove the license dependency. If you want to continue with the older versions of hub and probes that require an extension of the license, contact Support so that they can assist you in extending the license (if required). For more information about how to take a backup of the licensing information, see Back Up the Licensing Information
