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
