The information in this document is related to all current PCA Versions
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
You are near or at max system capaicty which can cause:
System performance issues such as your, opt to reach 100% or services crashing consistently.
You are not able to deploy anymore endpoints per your Open Virtualization Format (OVA) and need a larger one.
Upgrade Small and Medium OVA's
Step 1. Please refer to the virtualization support guide for your version, in order to determine the extra resources needed.
Step 2. Although there have been no reported issues, it is always best to create a backup.
Take a Virtual Machine (VM) Snapshot
Step 1. Log in to Vsphere as an admin user.
Step 1. Right-click on the VM in Vsphere.
Step 2. Select Snapshot>>Take Snapshot. Check the status at the bottom of Vsphere window to monitor completion.
Take a PCA Backup
Step 1. Navigate to System Administration>>Backup Settings>> Select New. Provide the required information based on your needs, i.e. if you want just the assurance data or assurance and analytics. Once the backup is complete, proceed to the next step.

Step 3. Log in to PCA Command Line Interface (CLI) as root and use port 26.
Step 4. Enter /opt/emms/emsam/bin/cpcmcontrol.sh stop.
Step 5. Navigate to you PCA VM and power down the VM.
Step 6. Right-click and Edit the VM settings in order to add the additional resources.
Step 7. Right-click in order to Power back on the VM. Wait 15 minutes.
Step 8. Log in to PCA as root and use port 26.
