In Replication Server version 11.0 and later, connect source returns an additional row that provides the Replication Server system version number and an upgrade locator.
The upgrade locator gives the origin queue ID of the last message written into the inbound queue before the system was upgraded. For details about the origin queue ID, see “Format of the origin queue ID”.
The upgrade locator is useful when you are creating a Replication Agent, upgrading from a pre-11.0 version of Replication Server to version 11.0 or later, and mixed-mode transactions (both applied and request functions) are in progress.
