Why use TransVault for our EMC to Exchange Migration?
TransVault delivers rapid and comprehensive migrations from EMC’s EmailXtender and EMC SourcOne back into Microsoft Exchange, Office 365 and other archive platforms such as Enterprise Vault.
- One Step – Migration is done at the API level in a single, synchronous step, requiring no interim stage or interim storage.
- Transparent to users – Users can access their data whilst it is being moved – there is no need to disable access to the archive. Shortcuts are seamlessly converted to point to the new archive store, ensuring the upgrade process is completely transparent to end users.
- Ensures Compliance – Throughout the migration process TransVault maintains a full audit trail to maintain chain-of-custody – this is an important consideration for compliant retention.
- Automatic Failover & Logging – TransVault keeps a complete error log, with the ability to automatically resume a migration task that fails for any reason (e.g. owing to a network outage or a corrupted item).
- Notes to Exchange Conversion – If you’ve been using EmailXtender or SourceOne for Notes, and you want to migrate to Exchange, TransVault delivers on-the-fly, high fidelity Notes to Exchange conversion.
- Advanced Features – TransVault enables high flexibility, including the ability to perform email address re-writes to address the needs of a company restructuring, etc.
Does TransVault Support Extractions from EMC Storage?
Yes. TransVault supports migration of archives that have been written to EMC DiskXtender, as well as a variety of media types, including EMC Centera devices, DVD-R, tape, or magneto-optical Ultra-Density Optical (UDO), WORM, WORM-tape, and Network Attached Storage (NAS).
What happens to shortcuts (stubs) when we migrate to Office 365?
TransVault provides a comprehensive shortcut management service that ensures users have a seamless experience when they migrate.
When moving to Microsoft Exchange (or Office 365), legacy EAS shortcuts are replaced (rehydrated) with the original item. You can also set policies that determine whether items are moved into Primary mailboxes or In-place Archives. For example, you could move items older than 2 years into archives, and keep everything ‘younger’ in the Primary mailbox.
Another key feature designed to ensure a great user experience is that TransVault synchronizes with the current status of users’ shortcuts as they exist in their mailbox at the time of the migration.
For example, where users have re-foldered their shortcuts ‘post-archiving’, TransVault ensures the corresponding items end up in the right folders post-migration.
Similarly, where users have deleted their shortcuts, you can configure TransVault not to migrate the corresponding item, as this is confusing and causes concern for end users when deleted items reappear.
How quickly can we move our archives from EAS to Exchange?
Migration speeds have been measured in excess of 2TB a day.
As well as running multiple threads on a single server and across single mailboxes, multiple TransVault servers can be configured to operate in parallel and:
- Extract from multiple maiboxes and multiple file stores at once from your EAS environment
- Migrate to many mailboxes simultaneously
- Have multiple migration tasks operating in parallel on individual extra large mailboxes
The transfer of emails to Exchange uses MAPI for optimum speed.
Note, however, that achieving best performance is dependent on many factors such as:
- Available network bandwidth
- Loading on the legacy email archive and your Exchange servers
- The speed of the storage subsystem on which the legacy archive sits
Your chosen archive migration partner can establish a proof of concept (POC) to establish likely throughput rates in your specific environment.
