Cutover Migration Task List Example
This sample task list covers a cutover migration approach. The scenario for
this task list is:
• The mid-sized company requires a simple, somewhat fault-tolerant
upgrade.
• In the event of failure, the company depends on nightly backups. The
system cannot be down more than one hour and cannot afford more
than eight hours of data loss.
• The environment includes development, test, and production systems.
This example does not repeat the preparation steps given in previous
examples. This section includes the following task lists:
• Set Up ASE 12.5 Environment on Development System
• Define Test/Acceptance Criteria—Regression Test Suites
• Define Fallback Procedures on Test System
• “Baseline” Older Environment on Test System
