BridgeAD is an Active Directory migration tool for managing identity and Microsoft 365 migrations through controlled workflows. It supports migrating Active Directory, Entra ID, Exchange, SharePoint, OneDrive, and Teams, with tools for assessing cloud estates and creating migration plans. The platform prioritizes operator control, dry-run validation, and audit evidence generation. BridgeAD’s four-phase approach includes Discovery for readiness assessment, Planning for mapping rules and rollback guardrails, Execution for dependency-ordered jobs with retry and monitoring, and Verification for checks and audit reports. It handles mailbox migrations across Exchange Online, Gmail, IMAP, and on-premises Exchange, along with Active Directory workflows like SID history and ACL restamping. Microsoft 365 features include Teams reconstruction, SharePoint and OneDrive transfers, and Entra ID synchronization. Features include dashboards, REST APIs, TLS encryption, and role-based access control.
