[omniORB] omniORB interoperable with different versions of itself?

[Steve Bowman]

Hi all,

We've a concern regarding the upgrade of our products.
We have a requirement that our customers are able to upgrade
their systems piecemeal, i.e. that they are able to have
concurrently running machines with different versions of our
product (and hence potentially omniORB). Are there any
guarantees regarding the interoperability of different
versions of omniORB? Are there any known issues?

Does anyone know whether the OMG has made any undertaking to
make changes to IIOP backwards-compatible?

Thanks for your help.

Cheers,
