Upgrade Routes

Upgrading the route allows the Replication Servers to exchange information about newer software features.

The route version is the earliest site version of the source and destination Replication Server. After you upgrade the source and destination Replication Servers on either end of a route and also set their site versions to a higher Replication Server version, you need to upgrade the route.

Upgrading a route rematerializes data in system tables, making information associated with new features available to a newly upgraded Replication Server. After upgrading, new types of information that were not previously allowed can be exchanged.

To display the current version number of routes that originate or terminate at a Replication Server, use the admin show_route_versions command.

To report the routes that you need to upgrade that originate or terminate at the Replication Server that you are upgrading, use admin version, "route".

There are two possible scenarios for route upgrade:

You must use sysadmin upgrade, "route" to upgrade routes if new features have been used at the source Replication Server.
You can use sysadmin fast_route_upgrade to upgrade routes only if you are sure no new features have been used at the source Replication Server.

Use sysadmin upgrade, "route" if you are not sure if new features have been used at the source Replication Server.

You cannot downgrade a route after you have upgraded it, and there are restrictions if you have mixed-version replication systems.
