Case Study: Air Lease achieves a cohesive Microsoft 365 environment with Proventeq SharePoint migration

Air Lease - Customer Case Study

Air Lease, a US aviation company and confirmed Microsoft house, wanted to move from iManage to SharePoint Online to create a more cohesive Office 365 environment. After ten years on iManage, the business was frustrated by limited adoption, restrictive external support, and the inability to meet specific legal metadata and date-retention requirements. Air Lease turned to Proventeq and its Migration Accelerator software to address these challenges.

Proventeq delivered a three-phase migration over six months, starting with discovery and analysis, then pilot migration, information architecture optimisation, and security/compliance remapping before a full-fidelity cutover to SharePoint Online. The solution preserved key metadata such as created and modified dates, enabled customer-specific document libraries, and added Power BI reporting, giving Air Lease better visibility, stronger internal support, and a more intuitive cross-device experience. The migration succeeded smoothly with an item-level audit trail, and Air Lease reported increased productivity and planned to continue using SharePoint for years to come.
