Keep the following information in mind about upgrading the Metasys or FX system software:
- When you upgrade an archive database to Release 14.0, the site is upgraded to Release 11.0, but its network engines can continue to run at, and be managed with, Metasys Release 5.2 and later. However, if you have a mixed site with network engines at older releases, make sure that you disable Advanced Security on the Metasys Server and on all devices that report to the server.
- From SCT at Release 14.0 and later, you can still add supervisory devices at older releases, but only from Metasys Release 5.2 and later. For example, if you upgrade the Site Director to Release 11.0, you can add and maintain supervisory engines at Releases 5.2, 8.1, 9.0.7, 10.0, and 11.0. However, you cannot add or maintain supervisory engines that are at a later release than the Site Director. For example, if the Site Director is at Release 10.0, you can add engines at Releases 5.2, 8.1, and 10.0, but you cannot add engines at Release 11.0.
- You can configure your Metasys site into logical representation of spaces and equipment. However, you cannot edit spaces and equipment in the SMP UI.
- You can upgrade devices to the latest release at any time.
- If you are upgrading SCT from Release 11.0 or earlier, you must uninstall the older release of SCT before installing Release 16.0. However, if you are upgrading SCT from Release 11.1 or later, you can upgrade to SCT 14.0 without uninstalling the older release of SCT.
- When you install SCT, the software is configured with a self-signed certificate by default. To indicate the security level, an orange connection status icon appears on the SCT login and user interface screens.
As part of upgrading network engines, use SCT to download their archive databases after the upgrade is complete. The download also restores the Security System database. After the download completes, issue the Archive Device command to each downloaded small-frame engine (NAE35, NIE39, NAE45, NIE49, NCE25, or NIE29s) to ensure that the security database is archived to non-volatile memory. This step is not required for large-frame engines (NAE55s and NIE59s).
- You can view the upgrade logs with SCT. To view the upgrade logs, use the Upgrade Log option under the Diagnostics menu.
