Updating a Data Replication Engine

Sometimes it is necessary to change or update a data replication engine. Switching replication engines with zero downtime is a topic of immense complexity.

Therefore, application availability can be ensured during the migration process.

Simplify Switching Live Replication Engines with Shadowbase Zero Downtime Migration (ZDM)

Customers have been using HPE Shadowbase Zero Downtime Migration (ZDM) for decades to upgrade their applications, database schema formats, file and table locations (or indices), operating systems, and perform a hardware refresh.

In these papers, we discuss how a data replication engine can be changed or upgraded without taking either the application or the database offline (of course, this approach also works in those simpler cases where an application outage is allowed).
