Distributed Control Systems (DCSs) for emerging industrial control applications impose new communication requirements that cannot be satisfied by current Industrial Ethernet protocols. As a result, industry is pushing the Time-SensitiveNetworking (TSN) standards as the de-facto Ethernet-based link-layer to fulfill these requirements. Adequate roadmaps are needed to support a smooth transition from Industrial-Ethernet-based legacy systems to TSN-based ones. In this context some works propose mechanisms to migrate, i.e. map, route and schedule, legacy traffic to TSN. However none of them considers traffic including streams with spatial redundancy requirements and, thus, they cannot be used to migrate legacy highly-reliable DCSs. The present TFM extends a previous toolchain to migrate, for the fist time, legacy critical traffic that includes spatially redundant streams. Particularly, since redundancy is costly, this TFM proposes and compares  two routing methods that consider one redundant stream per traffic.
