Migration begins with inventory
Before changing DNS, we identify active mailboxes, aliases, groups, mailbox sizes, historical data, devices and dependencies that must survive the move.
Business Email Migration
A business email migration should preserve mail history, establish the new mail environment, control DNS cutover and verify sending and receiving before the old system is retired. DSDillon plans the move around continuity rather than treating it as a simple mailbox switch.

Changing MX records too early can split mail between providers.
Old messages may be stranded if migration scope is not checked first.
Users can lose access during cutover when credentials, aliases and devices are not planned.

The new environment is configured before mail routing is changed. DNS, authentication and receiving tests are coordinated so the organization has a clear transition point and rollback path.
Sending, receiving, aliases, historical data and access are checked before the previous service is considered finished.
