Case studiesHosting migration with DNS cutover and dependency mapping
When a move touches DNS, TLS, redirects, and mail paths, the failure mode is rarely the file transfer alone. This draft follows the hosting framing: map dependencies, run cutover in order, validate after the change is live.
A production site needed to move to a new hosting stack while DNS and related records stayed coherent. TLS, redirects, and mail-related paths had to survive the switch—without a clear map of what owned each layer, cutover risk was high and rollback was unclear.
Map hosting, DNS, TLS, redirects, and email-related dependencies first. Sequence work with rollback thinking, execute the DNS cutover with checks defined before the window, then run post-change validation beyond the moment of switch—not stopping at “DNS flipped.”
