Migration and relocation: the exit is the easy half
In a migration, the exit is the easy half. What makes it hard is everything that has to be already running on the other side.
Free, no obligation. A call back to confirm the details, then, if you agree, a quote from one qualified provider covering your sites.
Dependencies, not transport
Moves rarely fail because a truck was late. They fail because something in the old room was still serving something in the new one, DNS, a licence server, an authentication path, a monitoring collector, a backup target.
The dependency map is therefore the first deliverable, and it is built from observed traffic rather than from documentation. It is also the second item of the decommission project plan.
Want this scoped for your own site?
Sequencing
- Establish connectivity between sites and verify it under load, not at idle.
- Move the services other things depend on first, and prove them.
- Move in waves grouped by dependency, not by rack position.
- Keep a rollback path for each wave, with a decision point and a deadline.
- Decommission only after a defined soak period, never on the same day.
That last point is where migration and decommissioning meet, and where pressure to close the old site early causes the most damage. How the two plans interlock is in migration and decommissioning, and the case of a cloud migration in its own article.
Scope the migration
Describe both sites and the target window. The call back sorts out which parts are genuinely parallelizable before a provider quotes.
After you send it: a call back, dialed by hand, to go through the scope with you. With your agreement, the scoped request then goes to a qualified provider covering your area.
