# XMS Admin Guide

> Operator-facing reference for running the Xloud Migration Suite — architecture, prerequisites, credentials, network ports, storage back-ends, and capacity planning.

## Overview

The Admin Guide is for operators who install, configure, and run XMS
(Xloud Migration Suite) for their organization. It covers the pieces that sit
behind the end-user migration experience — service architecture, source
credential design, network access, storage back-ends, and capacity planning.

<Note>
  If you are looking for the workflow to actually migrate a workload, start in
  the [User Guide](/services/migration/user-guide).
</Note>

<Warning>
  XMS requires network access from the migration workers to both the source
  hypervisor API and the Xloud platform services. Review the
  [Network Ports](/services/migration/admin-guide/network-ports) page before
  onboarding a new source environment.
</Warning>
