There are a small number of known interoperability issues between 1.8.3 clients and 2.0.0 servers that were found during release testing, and while some of them were fixed for the final 2.0.0 release there are a couple of issues that also needed changes appearing in the 1.8.4 client. I assume you are already aware that 1.8.x clients cannot use Kerberos authentication in any form, so in that regard 1.8.x is not compatible with 2.0 if you require Kerberos auth. > Officially it is not compatible and/or supported?

I'd have to dig a bit to recall what the 1.8.3 <-> 2.0.0 interoperabilty issues were, but they were fairly minor (e.g. one was an issue with early replies from adaptive timeouts, which I think was fixed in the 2.0.0 server) and it can't hurt to do some testing in your environment.
