This is a common requirement, and so far, a straightforward process. The complexity arose when they needed to upgrade their application model, which was taking a long time to run due that most of the tables required a full rewrite.</p> <p>The Django migration was taking several hours to run, which made a blue/green upgrade and subsequent migration execution unfeasible due to the long downtime it would incur.</p>
