## Overview

Hystax Acura Live Migration supports automated, VM-centric Relocate scenarios from VMware, bare
metal, and other supported source platforms to STACKIT. It replicates machine data and metadata in
the background, creates target-specific migration plans, and lets teams validate workloads through
isolated test migrations before a planned cutover.

Hystax publicly documents STACKIT as a target cloud type. The integration uses STACKIT
service-account credentials for cloud discovery, replication, and recovery workflows in a target
project.

## Typical capabilities

- **Background replication**: Synchronizes VM data and metadata while source workloads continue to
  run, using internal or external replication agents depending on the source platform.
- **Isolated test migrations**: Runs repeated functional and performance tests in an isolated target
  environment before the final migration window.
- **Migration plans and transformation**: Orchestrates application startup order and supports P2V
  and V2V transformation with target-specific compute, storage, network, and boot settings.
- **Controlled cutover and rollback**: Provides a planned final switchover with a rollback path when
  acceptance criteria are not met.
- **Multi-tenant operations**: Gives service providers one control plane for migration projects
  across multiple customers.
- **Disaster recovery**: Supports active-passive protection, test failover, and failback workflows in
  addition to one-time migration projects.
- **Storage and ransomware controls**: Supports configurable replication storage and can detect
  abnormal incremental replication growth to suspend affected machines.

## Typical fit criteria

- **Large or heterogeneous VM estates**: Useful when many workloads must move from VMware, bare
  metal, or multiple supported clouds through a consistent process.
- **Downtime-sensitive workloads**: Background replication and rehearsed test migrations reduce the
  work left for the final cutover window. Actual downtime depends on workload startup and
  validation time.
- **Migration factory or provider model**: Multi-tenancy, migration plans, and repeated tests support
  parallel customer projects and migration waves.
- **Combined migration and recovery needs**: Suitable when the same deployment should also support
  ongoing replication, failover testing, or disaster recovery after migration.

## STACKIT deployment prerequisites

- **Hystax Acura controller**: A STACKIT VM created from the Hystax Acura golden image with 8 vCPUs,
  16 GB RAM, and a 200 GB SSD disk.
- **Cloud agent capacity**: A target or failover project must permit a cloud-agent VM with 2 vCPUs,
  4 GB RAM, and a 20 GB disk.
- **Authentication and networking**: A dedicated STACKIT service account, its key, the documented
  ingress rules, and routable connectivity between the controller and cloud-agent network are
  required.
- **Platform services**: Deployment requires an SMTP server with TLS or SSL encryption and a Hystax
  license key.
- **Workload validation**: Confirm source-platform support, dependencies, target sizing, network
  mappings, recovery objectives, acceptance criteria, and rollback triggers before each wave.
