To upgrade the Infrastructure Management server on the secondary computer
- Stop the primary TrueSight Infrastructure Management server.
- Synchronize the cell database (MCDB) on the primary and secondary servers:
- Delete all content in the installedDirectory\TrueSight\pw\server\var\<secondary_cell_name> folder (for example, pncell_<host name>#2) of the secondary server.
- Copy all content from the installedDirectory\TrueSight\pw\server\var\<primary_cell_name> folder (for example, pncell_<host name>#1) of the primary server to the above location on the secondary server.
- Upgrade the secondary server. See:
(Using the wizard) Upgrading-the-Infrastructure-Management-server-in-the-standalone-mode-using-the-wizard
(Silently) Upgrading-the-Infrastructure-Management-Server-in-the-standalone-mode-silently - Stop the secondary TrueSight Infrastructure Management server.

- Copy all content from the installedDirectory\TrueSight\pw\server\var\<secondary_cell_name> folder (for example, pncell_<host name>#2) of the secondary server to the above location on the primary server.
- Start the primary TrueSight Infrastructure Management server.
- Verify that the primary server is the active node by running the pw ha status command.
- Start the secondary TrueSight Infrastructure Management server.

To detect the active and standby nodes, check the HTTP response codes for the following URLs:
https://<primary hostname>/jsp/ShowError.jsp
https://<secondary hostname>/jsp/ShowError.jsp
HTTP response 200 - active node
HTTP response 503 - standby node
