Your environment has several components such as DB2® servers, DB2 clients, database applications, scripts,
routines and tools. 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 10.1:
- Review the new, deprecated, and discontinued functionality for DB2 Version 10.1 and for any releases between the release you are upgrading
from and DB2 Version 10.1.
- Plan how to and modify your database applications and routines.
Ensure that they run successfully in DB2 Version 10.1.
- Set up a DB2 Version 10.1 test server and create test databases.
- Test your database applications and routines on a DB2 Version 10.1 test database to determine whether they run successfully.
If your application requires a client, use a DB2 Version 10.1 client.
- Upgrade your DB2 servers
and clients in a test environment. Determine what the issues are and
how to resolve them. Use this information to adjust your upgrade plan.
- Upgrade your DB2 servers
to DB2 Version 10.1 in your production environment. Ensure that they operate
as expected.
- Upgrade your clients to DB2 Version 10.1 in your production environment. Ensure that your clients
operate as expected.
- Test your database applications and routines in the DB2 Version 10.1 upgraded environment to determine whether they run
as expected.
- Make your upgraded environment available to users.
After you have a strategy that will give you the outline for your
upgrade plan, you can define the upgrade plan details for each component
in your environment. An
upgrade plan should include for
each component:
- Upgrade prerequisites
- Pre-upgrade tasks
- Upgrade tasks
- Post-upgrade tasks
If you have previous upgrade plans, review them and compare them
with the upgrade plan for
DB2 Version 10.1. Include in your new plan any steps 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
additional resources and up-to-date information about the upgrade
process as they become available. These resources include educational
material, white papers, and webcasts for upgrade.
Finally, plan to remove the use of deprecated functionality and
incorporate new functionality from DB2 Version 10.1. Although you are only required to remove the use of
discontinued functionality, you should also plan to remove the use
of deprecated functionality after upgrade because they will become
unsupported in a future release. Also, you should take advantage of
new functionality for your database products, applications, and routines
to enhance functionality and improve performance.
