Windows AD Migration Specialist

Perform user migrations between two Microsoft 365 tenants according to detailed instructions and checklists.

Transfer and verify the correct functionality of:

• mailboxes (Exchange Online);
• OneDrive for Business (user personal storage);
• Microsoft Teams (chats, teams, memberships, basic settings);
• calendars (meetings, recurring events, delegations, rooms/resources — per instructions).

Review existing user permissions in the target tenant and partially restore these permissions (groups, roles, access to SharePoint / Teams / mailboxes) based on a predefined template.

Work with the source tenant:

• prepare mailboxes as required (e.g., disable licenses, convert to shared mailboxes, archive, etc. — according to instructions);
• set up required forwarding/redirects and auto-replies for migrated users;
• ensure proper “mailbox deprovisioning” (deactivation, archiving, deletion according to policy).

Maintain accurate records of completed operations in spreadsheets/tracking systems (migration status, errors, execution time).

Escalate non-standard issues or errors to a senior engineer/architect as per the process.

Communicate with the service desk and, when necessary, with end users using predefined response templates.
