You do not need to install an earlier release of 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 SCT, the archive must be at the same release as 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 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 SCT, or you need to open an archive database in an earlier release of SCT, contact your local Johnson Controls representative for assistance.
