ASE 15 Upgrade Checklist for Upgrading from ASE 12.x Sybase ASE 15

STEP 1.19: CREATE A TEST PLAN
1.19.1: GOALS
While the Tactical plan covers the steps to follow on upgrade day, the test plan must cover the
functional and performance testing of your application environment. It should also define success or
failure criteria for each critical module. Continued testing should follow until all criteria are met.
Knowing how and what to test will avoid serious unexpected problems in production. This testing
phase is critical to the success of your upgrade, since ASE 15’s new features will affect your current
settings and query performance.
As part of a “best practices” approach, you need to build a robust test environment in order to run,
verify, and tune your server configuration, your query performance, your query results and your
upgrade procedures. Further, this test environment should simulate your production environment and
application workload as close as possible in order to achieve the best results. See Step 2.1 below for
more details.
1.19.2: CONSIDERATIONS
Evaluate the type of testing strategy you want to use, and then select an appropriate method for
testing your application. Several different strategies are documented in “Chapter 6 Ensuring Stability
and Performance --- Summary of testing techniques”, at the following link:

Identify the functional areas of your application that are critical to your business and to the success of
the upgrade. These could include the following:
o
o
Periodic batches (nightly, weekly, monthly, etc).
Functional modules including, but not limited to:
• Online functionality
• Upstream/downstream interfaces, data feeds, etc.
Determine the success criteria for each module to determine acceptable variances in performance or
resource utilization after the upgrade/migration.
Develop “Single User” functionality tests for all (or at least the most critical) modules. The plan must
include at least one end-to-end test of all the critical modules identified.
Develop application “Stress Tests” that simulate peak workloads wherever possible.
Develop a plan to test the new configurations and features described in the Pre-Upgrade Planning
section of this document. Identify the optimal settings for your applications when using these
features.
Develop a plan to build a test environment that simulates your production. This will ensure the
validity of your testing and the usefulness of any tuning or configuration changes you make as a
result of your testing.
Plan for a second test cycle using any later ESDs released by Sybase subsequently to the start of your
testing. These may include fixes for issues encountered during testing saving valuable time later.
