MSC link definitions in an IMSplex

During the migration process from an MSC network to an IMSplex, you can retain your MSC link definitions for as long as you have a need for them. This allows you to test the IMSplex with shared queues environment and then revert to the MSC network to make adjustments.

After you have established the IMSplex with shared queues, you should not add new MSC links between the IMS systems in the IMSplex. If you attempt to start an MSC link between two IMS systems within the same IMSplex with shared queues, IMS issues message DFS2149 and aborts the link startup.
