Understand the rollback options

At any point during the migration process until the very last phase, if you hit any unexpected issue and need to (in effect) "rollback" the migration, you can always easily revert your client applications to connect directly to Origin.

The migration can be started from scratch once the issue has been addressed.

Here’s an illustrated view of all the migration phases. Click the components to open a larger view. Click again to return to the original view.

Migration phases from start to finish.

After moving your client applications off the ZDM Proxy instances (Phase 5), writes are no longer sent to both Origin and Target clusters: the data on Origin is no longer kept up-to-date, and you lose this seamless rollback option. This is the point at which you commit to using Target permanently. The ZDM Proxy deployment can be destroyed, and Origin is no longer needed by the client applications that have been migrated.

However, should you decide to move back to Origin at a later point, or move to a new cluster entirely, you can simply execute the same migration process. In this case, the new Origin will now be the former Target, and the new Target will be whatever cluster you wish to migrate to (which could even be the former Origin).
