Enterprise Vault to Office 365 migration

Veritas Enterprise Vault has long served as a trusted enterprise information archiving solution, helping organizations archive data from Microsoft Exchange, SharePoint, file systems, and emails for legal, compliance, and eDiscovery purposes. While it was once a critical component for robust data retention, the rise of modern, cloud-native platforms has shifted how organizations approach archiving. Today, many Microsoft 365 users view Enterprise Vault as supplementary or even outdated, particularly given that Microsoft 365 offers integrated archiving, compliance, and eDiscovery tools out of the box. Moreover, Enterprise Vault archives—whether stored on-premises or in third-party clouds like AWS or Azure—can create additional administrative complexity and cost.

EdbMails PST migration tool is a trusted Microsoft partner for migrating PST archives from Enterprise Vault to Office 365, equipped with advanced features designed for efficiency and security. Its granular control option enables users to precisely select and migrate only the necessary data, ensuring a tailored migration process. EdbMails also supports multilingual environments, making it highly adaptable for organizations with diverse language requirements. The platform employs secure authentication protocols such as OAuth 2.0 and TLS encryption, ensuring robust protection of data throughout the migration. Additionally, EdbMails delivers significant cost savings, with pricing up to 50% lower than competitors, making it an affordable yet powerful option for businesses looking to modernize their archive management without compromising on quality or security.
