If you are upgrading your clients to the latest version or release
of DB2 Connect™, you need
to consider the following changes in support and resolve them before
you upgrade:
- Upgrade essentials for DB2® servers
and clients also apply to DB2
Connect servers
-
Upgrade support and restrictions for DB2 servers and clients also apply when you upgrade
your DB2 Connect server.
- Review upgrade essentials for DB2 servers to
determine additional changes that impact your upgrade and how to address
any issues.
- Review upgrade essentials for clients ,
especially Connectivity support between clients and DB2 servers. Connections to the latest version
or release of DB2 Connect servers
from a client release two or more versions earlier are not supported.
- Review
the need to opt for DB2 Connect client,
instead of DB2 Connect server,
to receive equivalent or superior function. You can reduce complexity,
improve performance, and deploy application solutions with smaller
footprints. For details, see the topic about client/server connection
options.
- New names and packaging of the DB2 components
In DB2 Version 9.7, the names and packaging of the DB2 components have been changed.
Refer to Component names have changed for
details on the new names and generic client names.
- Upgrade recommendations for DB2
Connect
-
The last two versions of the clients can connect to the latest
version or release of DB2
Connect servers. The only restriction is that new features are
not available to the clients from the previous versions and releases.
However, it is not likely that you need access to these new features
because your existing applications do not use them.
If you choose
to upgrade your clients first, you need to be aware that there are
known limitations about the support for connectivity from a current
version or release of the client to DB2 Connect servers from two versions
ago. Check the current version or release of the incompatibilities
with previous releases, see if these limitations apply to your application
in order to take necessary actions.
Perform the pre- and post-upgrade
tasks to ensure a successful upgrade.
