What makes an EMC SourceOne migration complex

A SourceOne migration must account for the structure of the archive, the people and requirements connected to its contents, and the readiness of each destination.

Multiple archive types

SourceOne can contain user email, journal, and file archives. Each may have different structures, ownership models, retention requirements, and destinations.

Distributed source environments

SourceOne environments may span data centers, business units, or regions. Systems, dependencies, and migration scope must be mapped before data begins to move.

Historical identities

Archived information may be associated with current and former employees, shared functions, and accounts that have changed. Those identities must be resolved so information reaches the correct destination.

Destination dependencies

Accounts, storage, permissions, licenses, and policies must be ready before users or archive populations can transition.

Continuing requirements

Legal holds, regulatory requirements, records policies, investigations, and other requirements may remain after SourceOne is retired. They must stay connected to the information they govern.

Manual coordination

Communication, provisioning, scheduling, transfer, validation, exception handling, and follow-up create numerous dependencies. Managing them through scripts and spreadsheets alone makes status and exceptions harder to track.

Retire an unsupported archive without losing control of its data

EMC SourceOne reached end of support on December 31, 2024. Years of archived information must remain protected and available as the organization moves to supported systems.

Support status | SourceOne no longer receives standard vendor support, updates, or continued development
Understand the archive population | Inventory messages, attachments, journal data, files, metadata, and associated identities.
Identify continuing requirements | Determine which legal holds, retention requirements, investigations, records policies, and other requirements must survive the transition.
Choose the right destinations | Direct each population to production, preservation, another governed destination, or disposition according to its continuing purpose.
Move and validate | Preserve source context, reconcile migration results, and resolve exceptions before decommissioning.
Complete the retirement | Retire SourceOne when required information is available from its new destination and the organization no longer depends on the old platform.

Orchestrate the migration from assessment to retirement

Context discovered at one stage informs the next. New information can always return to refine earlier decisions.

Review the SourceOne environment and archive scope

Begin by reviewing the SourceOne environment and building a view of the archive data included in the migration.

Assess | Review the SourceOne environment, archive types, data volumes, user populations, system dependencies, target destinations, and project requirements.
Connect and Inventory | Establish approved connectivity and create a centralized view of the email, journal, and file archives included in the migration.

Keep SourceOne data complete, traceable, and usable

A migration succeeds when information remains complete, traceable, and usable after SourceOne is retired. ES1Complete carries source context forward, records migration outcomes, and keeps exceptions visible throughout the transition.

Preserve content and metadata

Carry forward messages, attachments, files, available metadata, timestamps, folder structures, and other source information required at the destination.

Keep journal records usable

Preserve journal records with the metadata and relationships needed for retention, search, and future investigation.

Resolve historical identities

Map archived information associated with active users, former employees, and shared functions to the correct destination identity or approved target.

Record each migration outcome

Connect source records to their destination results so migrated, excluded, failed, and unresolved items can be traced.

Treat each destination differently

Process email, journal, and file archives according to destination requirements rather than forcing every population through the same migration path.

Surface and resolve exceptions

Identify inaccessible content, identity conflicts, unsupported items, and processing failures for investigation before completion.

Coordinate large SourceOne migrations without losing visibility

ES1Complete uses Cloudficient's cloud-native platform to automate and orchestrate the migration project. Workloads scale to the requirements of the project without a large fixed deployment of on-premises migration servers.

Preconfigured workflow steps

Use reusable steps for provisioning, communications, license assignment, migration, validation, exception handling, and follow-up.

Archive-specific workflows

Apply different workflows to email, journal, and file archives, or configure them by business unit, region, user group, or destination.

Centralized progress tracking

Track users and archive populations through their assigned workflows while maintaining a project-level view of progress and exceptions.

Automated coordination

Automate repeatable activities and handoffs so teams do not have to coordinate each user or population manually.

Specialist managed delivery

Cloudficient specialists oversee progress, investigate issues, and guide the approved migration plan through completion.

Controlled data movement

Protect information through encrypted transfer, authorized access, controlled processing, and documented handling throughout the migration.

Verify what moved before SourceOne is retired

ES1Complete maintains a record of how each user and archive population progresses through the migration. This provides evidence of what has been completed, what remains, and where additional action is required.

Source-to-destination reconciliation and traceability

Compare approved source populations with destination results to confirm what was processed. Use available fingerprints and migration records to support traceability from SourceOne to the destination.

Exception reporting

Identify items, users, and archive populations that could not be processed as expected, including their current resolution status.

Coexistence visibility

Maintain a clear view of migrated and remaining populations while SourceOne and the target environment operate in parallel.

Final sign-off

Confirm that approved data has reached its destination and that unresolved exceptions have an agreed treatment before decommissioning proceeds.

LEGAL CONSIDERATIONS Keep legal and retention requirements intact

SourceOne may hold information subject to legal hold, regulatory retention, records policies, audits, investigations, or other continuing obligations. These requirements need to remain supported through migration and after the source platform is retired.

Cloudficient helps organizations:

Account for applicable holds and retention requirements during planning.
Apply different treatments to user, journal, file, leaver, retained, or legally significant data.
Maintain traceability as information moves between systems.
Document migration and exception decisions.
Confirm that required data is available in the destination before decommissioning.
Preserve a complete record of the migration process.

Prepare the right destination for each SourceOne archive

ES1Complete supports different destinations because user, journal, and file archive data may have different accessibility, legal, retention, and operational requirements.

Microsoft 365

Move user archive and appropriate file archive data into Exchange Online, SharePoint, or OneDrive when employees need continued access. Preparation may include identity mappings, target locations, permissions, licenses, and migration schedules.

Expireon

Move journal, historical, leaver, or legally significant data into Expireon when it must remain governed and accessible outside an active user environment. Preparation may include retention, historical ownership, access, and disposition requirements.

Explore Expireon

Combined destination strategy

Use Microsoft 365 and Expireon together when SourceOne contains a mixture of active-user content and information with different legal, retention, or operational requirements. ES1Complete applies the approved treatment to each archive population.

What ES1Complete helps you achieve

ES1Complete® helps organizations move required operational information, validate the outcome, and retire SourceOne with a clear record of the transition.

Complete the retirement

Move required operational information into supported destination systems and validate the results before SourceOne is decommissioned.

End the legacy infrastructure dependency

Retire the servers, storage, networking, maintenance, and administrative work required solely to keep the archive accessible.

Reduce manual coordination

Automate repeatable work across communications, provisioning, licensing, migration, validation, and exception handling so internal teams can focus on approvals and issues.

Keep a clear migration record

Maintain source-to-destination traceability, validation results, exceptions, and project decisions so teams can see what moved, what did not, and why.

Build a clear path out of SourceOne

Assess the source environment, prepare each destination, automate the migration workflow, and retire SourceOne with a verified record of the outcome.
