Your environment has several components such as DB2® servers, DB2 clients, database applications, routines,
tools, and scripts. Planning your upgrade requires a thorough understanding
of the upgrade process of each component in your environment.
First, devise a strategy on how to approach your environment upgrade.
You must determine the order in which you are going to upgrade each
component. The characteristics of your environment and the information
in upgrade essentials, especially the best practices, and restrictions
can help you determine your strategy.
The following is an example of a good
upgrade strategy in
which you test your database applications and routines and determine
that they run successfully in
DB2 Version 10.5.
- Review the new, deprecated, and discontinued functionality for DB2 Version 10.5 and for any releases between the release you are upgrading
from and DB2 Version 10.5.
- Create a plan to modify your database applications
and routines. Verify that they run successfully in DB2 Version 10.5.
- Set up a DB2 Version 10.5 test server and create test databases.
- Test your database applications and routines on a DB2 Version 10.5 test database to determine whether they run successfully.
If your application requires a client, use a DB2 Version 10.5 client.
- Upgrade your DB2 servers
and DB2 clients in
a test environment. Determine the issues and solutions. Use this information
to adjust your upgrade plan.
- Upgrade your DB2 servers
to DB2 Version 10.5 in your production environment. Verify that the servers
operate as expected.
- Upgrade your DB2 clients
to DB2 Version 10.5 in your production environment. Verify that the clients
operate as expected.
- Test your database applications and routines in
the DB2 Version 10.5 upgraded production environment to determine whether
they run as expected.
- Make your upgraded environment available to users.
After you devise a strategy that gives an outline of your upgrade
plan, you can define the upgrade plan details for each component in
your environment. An
upgrade plan must include the following
details for each component:
- Upgrade prerequisites
- Pre-upgrade tasks
- Upgrade tasks
- Post-upgrade tasks
If you have previous upgrade plans, review and compare them with
the upgrade plan for
DB2 Version 10.5. Include in your new plan any steps that are related
to internal procedures to request access, software installation, or
other system services within your organization.
Review also the DB2 upgrade
portal at www.ibm.com/support (formerly known as DB2 migration portal) that provides access to
more resources and up-to-date information about the upgrade process
as they become available. These resources include educational material,
white papers, and webcast for upgrade.
Finally, plan to remove the use of deprecated functionality and
incorporate new functionality from DB2 Version 10.5. Although you are only required to remove the use of
discontinued functionality, you must also plan to remove the use of
deprecated functionality after upgrade because they will become unsupported
in a future release. Also, you must take advantage of new functionality
for your database products, applications, and routines to enhance
functions and improve performance.
