If you are using the Global Cardholder Synchronizer (GCS) role in your system, there are important limitations that you must be aware of when you upgrade your system to 5.8.
The Global Cardholder Management (GCM) module was rewritten in Security Center 5.7 GA to improve efficiency and scalability. Because of this enhancement, the Security Center 5.7 Directory is no longer backward compatible with earlier versions of Global Cardholder Synchronizer (GCS) roles.
For a GCS role () to connect to a running Security Center 5.8, the following criteria must be met:
- The minimum Security Center version of the sharing guest is 5.7.
- The Security Center version of the sharing host is equal to, or higher than its sharing guests.
The following table shows the compatibility between sharing hosts and sharing guests running different versions of Security Center:
|Sharing host version||Sharing guest version||Compatible|
|5.8||5.6 or earlier||No|
