From our testing it looks like you can use DevTest 10.1 Workstation to login to 10.2 or 10.3 on the server (registry). Would there be any downsides to doing this? That way we could upgrade to 10.2 or 10.3 on the server and users can continue using 10.1 workstation until their 10.2 workstation as been installed. Let me know if you have any comments.
Sorry, Garry, while this might work incidentally, it is not supported. Product documentation reads about Mixing Component Versions:
The registry and all the underlying components, including DevTest Workstation, must belong to the same release. Mixing component versions under a registry is not supported.
The Enterprise Dashboard is backward compatible through version 8.0 and supports connections from registries of multiple versions. However, the Enterprise Dashboard itself must be the most recent version. For example, Enterprise Dashboard 10.2 can accept connections from 8.0 and 8.4 registries. Enterprise Dashboard 8.4 cannot accept connections from a 10.2 registry.
Ulrich is right, it is not supported and never has been.
Ok- thanks it was worth a try.
