Fortunately, I took snapshots of my vApp before the upgrade. I highly recommend this, even if you aren't concerned about the heat maps. Just be sure to do a "Power Off" of the vApp before taking snapshots of the UI and Analytics VMs.
Anyway, for backing up the heat maps see these instructions from the release notes for 5.0.1 build 677931 -
Custom Analysis heat maps are not preserved after upgrade from vCenter Operations Manager 5.0 to 5.0.1
During the upgrade, vCenter Operations Manager 5.0.1 overwrites the configuration files that contain the heat map settings. As a result, the custom heat maps that you created in vCenter Operations Manager 5.0, are no longer found on the Analysis tab.
Workaround: Create a backup copy of your heat map configuration files before you initiate the upgrade.
- Log in to the UI VM as root user.
- Navigate to folder /usr/lib/vmware-vcops/tomcat/webapps/vcops-vsphere/WEB-INF/classes/, and create a backup copy of the heatmapConfigs.xml file to a folder outside the installation path.
- Navigate to folder /usr/lib/vmware-vcops/tomcat-enterprise/webapps/vcops-vsphere/WEB-INF/classes/, and create a backup copy of the heatmapConfigs.xml file to a folder outside the installation path.
- After the upgrade, use the backup copies of the heatmapConfigs.xml files to update the new heatmapConfigs.xml files with your custom settings.
