Troubleshooting online upgrade

This section lists common issues you could encounter during an online upgrade.

Redundant servers fail to communicate

I cannot make my redundant servers communicate and I keep getting the hardware alarm “Redundant Server not found”.

  1. Check the [LAN]EarliestLegacyVersion parameter value.
    • If upgrading from v7.20 use [LAN]EarliestLegacyVersion=7200.
    • If upgrading v8.0SR1 or v8.1 use [LAN]EarliestLegacyVersion=7500.
    • If upgrading v8.2 use [LAN]EarliestLegacyVersion=8000.
    • Run the Setup Wizard and set both servers to Networked mode.
  2. Set the same server password on both servers in the Setup Wizard (see Configure Server Password in installed help).

System is performing slowly even though hardware and software requirements are met

Check your system’s power options: Control Panel > Hardware and Sound > Power Options > Create a Power Plan > select High performance.

Remove Upgrade related parameters

After completing the upgrade process and confirming that runtime is fully functional, remove or update the following .INI parameters.

NOTE: You will need to restart the servers after changing the parameters for the changes to take effect.

  • [Alarm]SavePrimary: remove this parameter.
  • [Alarm]SaveStandby: remove this parameter.
  • [Debug]Kernel = 0: this is to enhance security and keep operators out of the kernel.
  • [LAN]EarliestLegacyVersion: remove this parameter.

The next time a user's passwords is changed after removing the EarliestLegacyVersion parameter, change all the passwords on one server and then roll out the updated project in the same order in which you conducted the online upgrade (primary server, clients, and then standby server).
