It depends on how your organization defines SOA.
IMO, the solution might well not be any different from a component standpoint. The primary difference might be in the interfaces exposed by the end-points–coarse-grained, application independent business level services as opposed to possibly low-level, application specified interfaces. For some integrations, you may already have a business level set of services.
Service-orientation does not prescribe any particular technology or components. Some even say that it has nothing to do with technology at all and that it is solely a business structure concern.
