Overview
The upgrade process for High-Availability (HA) installations is identical to that for non-HA installations. Follow the standard upgrade procedure as detailed in the relevant version specific upgrade guide, see Upgrade Guides.
Notes:
When upgrading HA installations be sure to employ the High-Availability installation image (statseeker_x.x.x_ha.iso), NOT the non-HA installation image.
The upgrade process is initiated by the Primary server. If a Secondary is present, it will be upgraded first and then the Primary will be upgraded. If no Secondary is present when the upgrade process is initiated, the Secondary will need to be installed post-upgrade using the same Statseeker version as the newly upgraded Primary.
If an Operating System upgrade is included in the process, then Statseeker will be available and considered Highly Available during the installation portion of the upgrade. Once installation is complete, both servers will be rebooted, at which time Statseeker will not be available and will only be considered Highly Available when both servers have restarted.
If the Operating System is not being upgraded, Statseeker will remain available on the Primary while upgrading the Secondary, but is not considered Highly Available until the installation on the Secondary has finished. Once the Secondary is upgraded, Statseeker will be shut down on the Primary and will not be available until the installation on the Primary has completed.
