Part 3 of Our Interview with CTO Michel Zehnder

9 Dec 2014 by olpa

Over the past couple of weeks we have discussed the benefits of using ArchiveShuttle over traditional migration approaches. Today, in the final part of our interview with our CTO, Michel Zehnder, we look at how Sync’n’Switch technology fits into the ArchiveShuttle approach to migration.

Michel, tell us a little about Quadrotech’s ‘Sync’n’Switch’ technology? How does it work?


To explain Sync’n’Switch effectively, let’s split it into 2 stages. The synchronization/data migration stage and the switch or user migration stage.

In Stage 1, we’re starting to synchronize items in the background from the source to the target system.

Stage One will not affect the usual functionality of the source system, everything works like before. New items are getting archived according to the policy that has been set up. Users can still access all items and use the functionality of the whole system.

In the background we’re fetching data and ingesting it in the target system in a temporary archive, which is not accessible and completely hidden from the user. This way we can start to sync the items, even weeks or months before the real migration occurs.

The Sync process will fetch also deltas. That means that if I get enabled today, and all my items have been synchronized to the temporary target, but new items were archived in the meantime, ArchiveShuttle will still find, identify, and synchronize them automatically.

Stage 2 is the actual migration of the archive. In stage 2 we start a workflow that takes care of the disable process on the source, the assignment of the temporary archive to the user and the processing of shortcuts, calendar items and all other stubs in the mailbox of the user. Typically Stage two is a fast process and takes just a few minutes per user.

This Sync’n’Switch approach ensures user-facing transparency and allows you to prepare the migration without any time pressure. There are several other advantages and automation possibilities, like having the move of an exchange mailbox trigger the migration of an archive, but that would be too complex to cover in a short answer. I’m pretty sure, we’ll cover that in one of our Quadrotech TV sessions as a video.
