Server Migration Factory

Servers rehosted wave after wave: replicated continuously, tested, cut over, with the source kept for rollback.

Servers move as they are, one wave at a time, along a line that repeats. The cloud's discovery tool reads the estate; its migration service copies each server's disks over the private link into a low-cost staging area, launches a test copy for the owners to check, then launches the final servers across two zones at cutover. DNS switches to them, the source stays untouched for rollback, and monitoring, backup and patching are on from the first day.

When to use it

  • Most of the estate rehosts: VMs and physical servers that move as they are
  • A fixed date sets the pace: a site exit, a licence renewal, an end of support
  • Many servers, each with a short cutover window and a rollback that must stay possible

Where FleziLift fits

FleziLift plans the factory; the cloud's tool moves the servers. The AS-IS assessment grades each server's facts by evidence (L0–L3) and the 7R rule tree sends the rehosts here, with target service, readiness and risk. The Wave Plan sets a foundation wave, a pilot of at most five non-production servers and waves that keep move groups whole, with gates from −28 to +3 days around each cutover; Go / No-Go decides by eight written rules, and the playbook names the cloud's own tool for every task.
