SCT allows you to maintain Release 5.2, 6.x, 7.x, 8.x, 9.0, 10.0, 10.1, 11.0, 12.0, and 13.0 engines in the site's archive.
The Site Director must be at an equal or higher revision to all the other servers and engines on a site. The Product Development Test Lab validates the latest revisions of a Site Director with a mix of Engines back to Release 2.0, including NCE, NAE35, NAE45 model engines.
SCT no longer requires the same revision as the Site Director when integrated with the ADS/ADX.
For sites installed with the Metasys UI, the Site Director server must be at Metasys Release 7.0 or later. Sites using the Rapid Archive Creation feature of SCT 11.0 or later to quickly configure their Metasys UI require the Site Director server to be at Release 8.0 or later.
