Directory servers are not backward-compatible. Perform this procedure if you are upgrading Security Center with multiple Directory servers to the latest version or release.

Before you begin

What you should know

  • During the upgrade, the Directory role is stopped. Consequently, Config Tool and most Security Desk features are not available. However, video that is displayed before the Directory service goes offline continues to be streamed in the Security Desk Monitoring task and saved to the Archiver. For example, video walls continue to display video streams. Access control continues to work as well, but operators are not able to use Security Desk manually to open doors, etc.
  • During the upgrade, each Directory server is upgraded separately. Consequently, the failover feature is not available.
  • License upgrades are only necessary for version upgrades (for example, from version 5.x to 5.7). It is not necessary to upgrade the license for service release upgrades (for example, from SRx to SRy).

Procedure

  1. On each of the secondary Directory servers in the Directory server list, stop the Genetec™ Watchdog service from the Microsoft Management Console (MMC) Service window.
    The secondary Directory servers are indicated with the expansion server icon (). Do not stop the main server ().
    The Genetec™ Server service is stopped on the secondary Directory servers. All roles that only run on secondary Directory servers are offline. Usually each Directory server is responsible for an equal share of the role and client connections. After the secondary Directory servers are stopped, any roles or clients previously connected to one of the secondary Directory servers are forced to reconnect to the primary Directory server. The clients briefly show the "Connection is lost..." message during this process. The roles and their entities appear as offline until they are reconnected.
  2. Upgrade the primary Directory server as the main server.
    The primary Directory server, also known as the main server (), is the only server that is still active before you start the upgrade process. While the main server is being upgraded, no Directory service is available on the system. Only some features remain functional.
    Security Center installer automatically stops the Genetec™ Server service on the main server, and restarts it after the upgrade.
  3. (Only applies to version upgrades) Activate your Security Center 5.7 license by doing one of the following:
    The Directory service is online. All expansion servers (except the secondary Directory servers) and client workstations that are not yet upgraded run in backward compatibility mode. Directory failover and load balancing are not yet available.
  4. From Config Tool, connect to the main server. Check that all roles, servers, and units are running as expected.
    The secondary Directory servers are still stopped (in red ). Any roles that only run on the secondary Directory servers are still offline.
  5. Upgrade the rest of the Directory servers as expansion servers.
    Security Center installer restarts the Genetec™ Server service after each upgrade. Directory failover and load balancing are still unavailable.
  6. (Only applies to version upgrades) Reactivate the Security Center 5.7 license for all your Directory servers.
    Directory failover and load balancing are now available.

After you finish

Upgrade the rest of your system according to your priorities and schedule.
IMPORTANT: Because adding backward compatible connections slows down the performance of the Directory, it is recommended only as a temporary solution before you are able to upgrade all servers and workstations.
