SourceOne to Microsoft Exchange Online

With the end of support for Dell EMC SourceOne, moving to Microsoft 365 and Microsoft Exchange is a logical step.  Bluesource is equipped and ready to facilitate the transfer of your crucial data to its new home. 

Maintaining SourceOne after end of life exposes organizations to technical, security, and compliance risks. 

Technical: The lack of technical support from Dell following SourceOne’s end of life can lead to increased downtime, more frequent system errors, and decreased compatibility with new software. The technical risks impact overall business operations, budget, and frustrate the IT team. 

Security: The lack of software updates and patches exposes cracks in the system. Legacy software like SourceOne can face cyberattacks and security breaches more easily than supported software.

Compliance: Unsupported software poses challenges for industry and federal data regulations. Outdated software increases the chances for financial or legal repercussions. 

EMC SourceOne

  • Can migrate as a journal, mailbox, or both.​
  • Shortcuts/Stubs in the mailbox can be removed or replaced.​
  • Extraction is done directly against the databases and storage.​
  • Exchange and Domino formats supported

Microsoft Exchange Online

  • Mail can be split between the mailbox and the archive​
  • Shared Mailboxes can be used for Journal Migrations​
  • Notes/Domino Address Mapping via Conversion Template or Mapping File

Why Choose Bluesource for SourceOne Migrations?

SourceOne migrations often include data spread across databases, journals, and, for many long-time EMC customers, legacy storage media. Getting all of it out cleanly, with chain of custody intact, is critical. Bluesource’s years of expertise in data migrations, ability to solve complex migration issues, and proprietary ArchiveMASH software make us a solid choice to handle any SourceOne to Microsoft migration.

Proven Track Record

In just 30 days, Bluesource migrated over 1 PB of email data for a single global enterprise customer with eight parallel migrations across different geographic markets. 

Direct Extraction

Bluesource extracts SourceOne data directly against its databases and storage rather than routing through an interim format; there are fewer moving parts and less risk of data loss in translation.

Built for Scale

Bluesource’s proprietary ArchiveMASH migration software supports over 62 data sources. That’s more than other common platforms, including Transvault.

How Bluesource Handles Shortcuts

“Removed or replaced” covers the outcome, but the policy behind it matters for user experience. Bluesource applies policy-based rules so the right content lands in the right place:

  • Age-based routing: items older than a set threshold can be routed to the in-place archive, while newer items land in the Primary mailbox.
  • Folder fidelity: if a user has re-foldered a shortcut after it was archived, the migrated item follows it to its current location, not its original one.
  • Deleted shortcut handling: if a user has deleted a shortcut, that item can be excluded from migration so it doesn’t reappear unexpectedly.

SourceOne To Microsoft Migration FAQs

Yes, SourceOne will be available during the migration however we recommend you put SourceOne into a read-only state during the migration.

The impact is minimal. Users will see shortcuts being replaced in their mailboxes and they can continue to access any email from SourceOne during the migration. Once the migration is complete, their data will be available in their mailbox or online archive.

Many organizations running SourceOne since it was EmailXtender have archived to a mix of data types over the years. Bluesource migrations can extract from:

  • EMC DiskXtender
  • EMC Centera devices
  • Tape, DVD-R, and magneto-optical (UDO) storage
  • WORM and WORM-tape media
  • Network Attached Storage (NAS)

If you’re not sure what your SourceOne environment is actually storing data on, we’ll find out during the Scoping phase.

Dell ended support for SourceOne on December 31, 2024. Dell no longer provides SourceOne with any support, including software maintenance, bug fixes, and security patches. Still running SourceOne puts organizations at risk. 

Bluesource maintains a complete error log for every migration and can automatically resume a failed task, whether the failure was caused by a network outage, a corrupted item, or another interruption, without requiring you to restart the batch from scratch.

Actual throughput depends on several factors specific to your environment:

  • Available network bandwidth
  • The speed of the storage subsystem the legacy SourceOne archive sits on, and the destination storage
  • The ingestion performance of the target archive system
  • How migration is sequenced against other project work, like target environment setup

Because of this, Bluesource starts every engagement with a Scoping phase that includes a proof-of-concept, so you get a realistic throughput estimate for your specific environment rather than a generic industry number.
