Migrating a classic Plone site to Plone 6 with Volto means more than moving records from one database to another. Free RichText HTML has to become structured Volto blocks, and that conversion is easy to get wrong quietly. At Interaktiv we built a live Migration Monitor that makes the whole pipeline visible in one place. It drives export, transform and import, and streams the run to a realtime dashboard: a visual map of which content types land where, throughput in objects per second, and what's already migrated versus what's still open. The most useful view sits at the end: an A/B comparison that puts the old page next to the migrated one, side by side, with a field level diff. You can finally see that the content survived. Export and import build on collective.exportimport, used as intended. What is new is the live orchestration, the monitoring pipeline and the A/B validation on top of it. The toolkit is alpha and still moving. We will show the architecture, how HTML turns into Volto blocks, and a live demo from the Monitor with the A/B comparison as the finale.
