I need google email addresses changed and moved over

Migrate 30 Google Workspace accounts from @number8events.com to @number8safety.com, ensuring each user’s full mailbox is preserved and assigned to the new address (e.g., wes@number8events.com → wes@number8safety.com). Configure domain and user aliases, perform secure mailbox transfers, and verify calendar and drive permissions. Implement forwarding so all incoming mail to @number8events.com routes to corresponding @number8safety.com addresses. Provide validation, post-migration testing, and documentation of steps performed.
