You upgrade the IBM® UrbanCode™ Deploy server,
agents, agent relays, and blueprint design server independently. Always upgrade agents, agent
relays, and the blueprint design server in addition to upgrading the server. In most cases, you can
install the new version over the old version.
About this task
In most cases, upgrade the server before you upgrade the agents.
Note: When you upgrade the
server, your plug-ins are upgraded to newer versions. Plug-ins are not necessarily compatible with
an earlier version. When you upgrade, previous versions of the plug-ins are kept on the server. You
cannot create processes with previous versions of plug-ins, but you can deploy snapshots that use
the old versions of the plug-ins.
