Release 3.0 nodes and SQL/MX Release 2.x nodes.
Running a later version of SQL/MX software on a development node that supports
a production node or nodes running an earlier version of SQL/MX software is not
allowed between SQL/MX Release 3.0 nodes and SQL/MX Release 2.x nodes.
Upgrading to a later version of SQL/MX or downgrading to an earlier version is
allowed.
You can use different SQL/MX software versions if the versions are within the
supported range and SQL/MX Release 3.0 nodes and SQL/MX Release 2.x nodes do
not interoperate in the same distributed network. For more information, see The
SQL/MX Environment on page 1-11.
