You do not need to install an earlier release of the SCT to work with devices that are at an earlier Release. You can use SCT Release 14.1 or later to manage devices that are at Metasys Release 5.2 or later.
Important: To open an archive in the SCT, the archive must be at the same release as the SCT. If
the archive is at an older release, SCT prompts you to upgrade it. However, if you
upgrade an archive in the SCT, you can no longer open that archive in an earlier release
of the SCT. For example, if you upgrade an archive to SCT Release 15.0, uninstall SCT
Release 15.0, and then install an older release, such as SCT Release 14.2, you cannot
open the archive in SCT Release 14.2.
If you uninstall the SCT and attempt to install an earlier release, the install may fail because of conflicting entries in the SQL database. If you need to install an earlier release of the SCT, or you need to open an archive database in an earlier release of the SCT, contact your local Johnson Controls representative for assistance.
