Unlike previous versions, Replication Agent for Microsoft SQL Server 15.1 is log-based and, to directly access the Microsoft SQL Server transaction log files, must be installed on the same Windows host on which the primary Microsoft SQL Server is running. Replication Agent for Microsoft SQL Server 15.1 cannot be installed on a UNIX or Linux host. Because of this, how you upgrade an existing Replication Agent instance depends on two things: (1) where the existing instance of the previous version of Replication Agent is installed, and (2) the current version of the primary data server.
When you use any of the upgrade procedures described in this section, the new Replication Agent for Microsoft SQL Server 15.1 instances will have the same configuration as previously existing instances, including instance names, administrative user IDs and passwords, and administrative port numbers.
Replication Agent for Microsoft SQL Server 15.1 does
not support downgrading to an earlier version.
