Understanding the Migration Process from On-Premise to Pure Cloud Archiving

  • Last updated on

If you already have a Barracuda Cloud Archiving Service subscription and mirrored data, contact Barracuda Technical Support for configuration options.

This article describes what to expect when migrating from a physical, on-premise Barracuda Message Archiver appliance to the pure-cloud Barracuda Cloud Archiving Service solution.

Migrating to the Barracuda Cloud Archiving Service may take some time depending on how much data you have on your local Barracuda Message Archiver appliance. If you have a large amount of data, migration can take anywhere from a few weeks to a few months. However, you can search your Barracuda Cloud Archiving Service data from the cloud interface or the local appliance once they are linked and the transfer begins.

Before Getting Started

Before migration can begin, you must complete the following.

  • Contact Barracuda Technical Support for direction on unstubbing mail currently stubbed to the Barracuda Message Archiver and restoring that mail to your Exchange server.
  • Verify your Barracuda Message Archiver is on the latest general available firmware release. If you cannot update your firmware to this version, contact Barracuda Technical Support.
  • If you do not have an active Barracuda Cloud Archiving Service license, contact your Barracuda Sales or Sales Engineering representative to obtain and activate a Barracuda Cloud Archiving Service license.

Migration Process

The following table describes the migration process.

Customer contacts Barracuda Technical Support and requests migration from the Barracuda Message Archiver to the Barracuda Cloud Archiving Service.

Barracuda Support initially makes adjustments to your cloud settings. Once these adjustments are complete, the support team will contact you (this takes approximately 10-20 minutes to complete).

Customer is directed to log in to the Barracuda Message Archiver, go to the ADVANCED > Cloud Storage page, and click Connect to Cloud Storage. Once connected, select Mirroring.Once that is done, data begins replication to the Barracuda Cloud Archiving Service.
Data begins flowing to the cloud as it begins populating the Barracuda Cloud Archiving Service.

Barracuda Support monitors the queues to make sure all data is transferred, and sets the device to SaaS so that the cloud is used as the sole data source for your emails once migration is complete.

Barracuda Support verifies all local data is transferred, and customer retires the appliance.Barracuda Support contacts customer once all local data is transferred, at which point the customer can retire the local appliance and use the Barracuda Cloud Archiving Service as the only data source for archived mail.
