Kaleris Achieves a Modern, Unified, and Branded Environment After Strategic Multi-Tenant Migration to Microsoft 365

The Challenge

• Fragmented Cloud Infrastructure:
  Operations were distributed across multiple Azure tenants, Google Workspace, and on-premises environments, leading to inefficiencies and increased security risks.
• Identity Management Complexity:
  Multiple identity sources and guest accounts complicated access control and user synchronization, including both corporate and unmanaged devices.
• Collaboration Workload Migration:
  Migrating sensitive workloads—such as email, Teams, SharePoint, OneDrive, and Google Workspace (GWS) workloads—into a single branded environment posed operational challenges. The migration needed to avoid data loss or service disruption, with minimal impact on business operations.

Google Workspace Workloads Included:

• GWS Mail – Email accounts and mailboxes
• GWS Drive – Personal and shared drive content
• GWS Shared Drives – Team-based shared folders
• GWS Sites – Internal sites and portals
• GWS Groups – Distribution and collaboration groups
• GWS Apps – Select productivity apps (with some exclusions)

Tool Selection and Change Management:
Selecting appropriate migration tools and preparing users for the transition required a robust change management strategy.

Proposed Solution

Kaleris sought a Microsoft technology specialist with deep migration expertise for both Microsoft and Google workloads, as well as strong adoption and change management capabilities. After extensive evaluation, Netwoven was selected as the Tenant migration partner due to their global delivery model, proven migration experience, robust change management, and strong security credentials.

The migration was structured into five key milestones:

1. Planning & Assessment
   • Kickoff meetings, access provisioning, and workload inventory
   • Security analysis and desktop deployment strategies
   • Change calendar and communication templates
2. Preparation
   • Tool procurement and validation (BitTitan, ShareGate)
   • New tenant configuration and readiness checks
3. Migration Execution
   • Test migrations followed by full delta migrations for M365 and GWS workloads
   • Domain switch and cutover communications
   • Device re-enrollment via Intune
4. Post Go-Live Support
   • Tier 3 support, drop-in sessions, and helpdesk knowledge transfer
   • Monitoring legacy tenant usage
5. Change Management Services
   • Updated FAQs, training content, and post-cutover support

Business Benefits

• Unified Cloud Environment: Consolidation of tenants into a single, secure Microsoft 365 environment.
• Improved Security Posture:
  Implementation of security baselines, multi-factor authentication (MFA), and Conditional Access policies.
