Replication Agent for Microsoft SQL Server must be installed on the same Windows host on which the primary Microsoft SQL Server is running, and Replication Agent for Microsoft SQL Server cannot be installed on a UNIX or Linux host. Before upgrading, consider where the existing instance of the earlier version of Replication Agent is installed and 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 instances will have the same configuration as previously existing instances, including instance names, administrative user IDs and passwords, and administrative port numbers.
