Overview
nxtMove (NxtSight Migration Suite) moves virtual machine workloads from VMware vSphere and standalone ESXi hosts into NxtSight. This guide walks through the end-to-end flow: register a source, discover workloads, validate compatibility, run cold or warm migrations, and complete cutover.Prerequisites
- An active NxtSight account with appropriate permissions
- Access to the NxtSight Dashboard or CLI configured with credentials
- API credentials sourced (
source openrc.sh)
Topics
Register a VMware Source
Add a vCenter or ESXi endpoint to the Migration panel with credentials
and optional datacenter scope.
Discover Workloads
Inventory VMs, disks, networks, and guest metadata through the vSphere API.
Preflight Assessment
Validate each candidate workload against NxtSight compatibility rules before
submitting a migration job.
Cold Migration
Power off the source VM and migrate all disks in a single pass — the
simplest path for workloads that can tolerate a maintenance window.
Warm Migration
Start a full sync while the source VM remains online, then replicate
only changed blocks until you schedule the cutover.
Cutover
Trigger the final sync and switch a warm migration job to its target
NxtSight instance.
Post-Migration Validation
Verify the migrated instance boots, has network connectivity, and mounts
all original disks.
Troubleshooting
Diagnose discovery failures, stalled syncs, stuck cutovers, and guest
boot issues after migration.
Choosing Cold or Warm
Use Cold Migration When
The workload tolerates a maintenance window, the disks are small, and
you want the simplest possible flow — one click, one pass, done.
Use Warm Migration When
The workload must stay online until cutover, disks are large, or the
initial sync would exceed an acceptable downtime window.
