How Xillio Addresses This 

Compliance-focused analysis with Xillio Insights

Compliance-focused analysis with Xillio Insights

We analyze your Archive Server environment to inventory partitions, assess retention policy complexity, identify legal holds, and map archive volumes. This analysis ensures SharePoint and Microsoft 365 architecture design maintains compliance requirements and identifies regulatory considerations before migration. 

Retention policy preservation

We map Archive Server retention periods and legal holds to SharePoint retention policies, Microsoft 365 compliance labels, or Azure immutable storage policies, ensuring retention dates remain accurate and enforceable post-migration with full auditability. 

Chain of custody documentation

Detailed migration logs, content validation reports, and audit trails document what moved, when, and how—providing evidence for compliance audits and litigation support.

What can make these migrations complex?

Archive Server: powerful archiving, aging infrastructure 

Aging Archive Platform

OpenText Archive Server has reliably stored email, documents, and business application content for decades—but the platform's age shows. Organizations face rising maintenance costs, limited vendor innovation, and challenges in integrating archives with modern collaboration and AI tools. Archived content sits isolated from daily work, accessible only through legacy clients or stub links that break when systems change.

Compliance-Driven Migration Complexity

The platform's strength—long-term retention with immutable storage and legal hold capabilities—creates migration complexity. You can't simply "move" archived content; you must prove chain of custody, maintain retention dates, preserve legal holds, and ensure audit trails remain intact for compliance and litigation purposes.

Why SharePoint Online and Microsoft 365 change the game

Modern Microsoft 365 Archiving

Modern archiving in Microsoft 365 makes archived content searchable alongside active content, accessible through familiar interfaces, and available to AI tools like Copilot. eDiscovery capabilities span archived email and documents in unified workflows. Retention policies and compliance labels replace Archive Server's separate retention management with integrated Microsoft Purview governance. 

Archive-Specific Migration Requirements

Archive Server migrations demand specialized handling that differs from typical content migrations. Archived content isn't just old documents, it's content under retention policies, legal holds, and regulatory requirements that must remain provable and defensible post-migration. 

Partition & Retention Structure Mapping

Archive Server's partition structure organizes content by retention periods, legal cases, or business units with different storage tiers and access policies. These logical separations must map to SharePoint sites, Microsoft 365 retention policies, or Azure storage tiers while maintaining compliance boundaries. 

Business Application Archive Dependencies

SAP and business application archives contain structured data references alongside documents—invoice images linked to SAP document numbers, HR records connected to employee IDs. Maintaining these relationships during migration to SharePoint requires careful metadata mapping and reference preservation. 

Retention & Legal Hold Preservation

Retention date preservation is critical: content with retention periods must maintain original dates, not reset to migration dates, ensuring compliance obligations remain met. Legal hold flags must carry forward with full auditability. 

FAQ

Can you preserve retention dates during migration to SharePoint?
Yes. We migrate content with original retention dates intact, not migration dates, ensuring compliance obligations remain met. Retention policies and legal holds map to Microsoft 365 compliance features with full auditability.
How do you handle archived email migration to Microsoft 365? 
We migrate archived email with full headers, attachments, and metadata to Microsoft 365 in formats supporting eDiscovery, legal hold, and compliance workflows—maintaining chain of custody for litigation readiness. 
What happens to stub links in user mailboxes? 
We provide options based on your requirements: migrate archived messages to active mailboxes, provide users access to archived locations in Microsoft 365, or maintain stubs with updated references to new archive locations. 
Can you preserve legal holds during migration?
Yes. We identify content under legal hold in Archive Server and apply appropriate Microsoft 365 retention policies or litigation hold features, maintaining hold status with audit trail documentation. 
Can this migration be executed in phases?
Yes. We support phased migrations by Archive Server partition, retention period, or business unit, allowing your archive infrastructure to remain accessible during transition.
Do you support migration to alternative archival storage? 
Yes. If Microsoft 365 isn't your target, we can migrate Archive Server content to other compliant archival platforms or Azure storage with appropriate retention and immutability configurations.
