Scanning Mode Best Practices

CRITICAL: Never Mix Scan Modes

A single machine must only be scanned using ONE mode. Never scan the same machine using both VMware mode and Physical scan mode.

Mixing modes creates duplicate records, broken relationships, and inaccurate reporting in Dr Migrate.

Understanding the Two Scan Modes

VMware Mode scans infrastructure via vCenter / VMware APIs and discovers VMs with their configuration and relationships. Physical Scan Mode scans machines directly at the OS / host level and treats each machine as an independent asset.

Each mode uses a different discovery mechanism and asset identity model. When you mix modes for the same machine, DMC cannot recognize them as the same asset.

Why This Matters

When the same machine is scanned using different modes:

  • DMC treats it as two separate assets
  • Duplicate or conflicting records appear in Dr Migrate
  • Relationships, metrics, and lifecycle tracking break
  • Reports and recommendations become inaccurate

Example: VM_1 is scanned via VMware mode from vCenter, then later scanned via Physical mode. Result: VM_1 appears twice in Dr Migrate with inconsistent data. This is not a supported configuration.

Which Mode Should I Use?

Your Infrastructure Recommended Scan Mode
VMware VMs managed by vCenter VMware Mode
Physical servers Physical Scan Mode
VMware VMs WITHOUT vCenter access Physical Scan Mode
Hyper-V hosted machines Physical Scan Mode
Nutanix hosted machines Physical Scan Mode
Standalone ESXi hosts (no vCenter) Physical Scan Mode
Mixed (VMs + Physical servers) Use both modes, but never overlap machines

Pre-Scan Checklist

Before running any DMC scan:

First-Time Scan:

  • What type of infrastructure am I scanning?
  • Do I have vCenter access?
  • Which mode is appropriate?
  • Have I documented this decision?

Subsequent Scans:

  • Have I scanned this infrastructure before?
  • Which mode did I use previously?
  • Am I using the same mode now?
If you’re about to use a different mode, STOP and contact support before proceeding.

For Mixed Environments (VMs + Physical Servers)

If you have both VMware VMs and physical servers:

Do this:

  1. List all vCenter-managed VMs → scan with VMware Mode
  2. List all physical servers → scan with Physical Mode
  3. Document which machines use which mode
  4. Never scan the same machine with both modes

Do NOT:

  • Scan vCenter VMs with VMware Mode, then rescan with Physical Mode “to get more data”
  • Re-scan an already-discovered VM using a different mode
  • Mix modes for testing or convenience

Key Rule

One machine. One scan mode. Always.

If you’ve already mixed modes, contact support immediately for data cleanup. For questions or uncertainty, escalate before scanning, not after.

SQL Server Discovery and Assessment

DMC supports discovery and assessment of SQL Server instances across all supported scan targets.

Supported SQL Server Versions

DMC supports discovery and assessment of SQL Server instances. Supported versions differ based on the operating system platform:

SQL Server on Windows:

SQL Server Version Support Details
SQL Server 2008 and above Full support for discovery and migration readiness assessment
SQL Server 2008 R2 Full support for discovery and migration readiness assessment
SQL Server 2012 Full support for discovery and migration readiness assessment
SQL Server 2014 Full support for discovery and migration readiness assessment
SQL Server 2016 Full support for discovery and migration readiness assessment
SQL Server 2017 Full support for discovery and migration readiness assessment
SQL Server 2019 Full support for discovery and migration readiness assessment
SQL Server 2022 Full support for discovery and migration readiness assessment

SQL Server on Linux:

SQL Server Version Support Details
SQL Server 2017 Full support for discovery and migration readiness assessment
SQL Server 2019 Full support for discovery and migration readiness assessment
SQL Server 2022 Full support for discovery and migration readiness assessment
SQL Server on Linux: SQL Server on Linux was introduced with SQL Server 2017. DMC supports discovery and assessment of SQL Server instances running on Linux starting from SQL Server 2017 and later versions.

SQL Server Discovery

SQL Server instances are automatically discovered during infrastructure scans (VMware, Physical, Hyper-V, and Nutanix). When SQL Server is detected on scanned machines, DMC collects instance information including:

  • SQL Server version and edition
  • Instance names and configurations
  • Database inventory
  • Server properties
Scan Target SQL Server Discovery Support
VMware SQL Server instances discovered on Windows and Linux VMs
Physical Servers SQL Server instances discovered on Windows and Linux servers
Hyper-V SQL Server instances discovered (via Physical scan mode)
Nutanix SQL Server instances discovered (via Physical scan mode)

SQL Server Assessment

SQL Server assessment is a separate workflow that can be performed after infrastructure discovery. DMC assesses SQL Server instances for Azure migration readiness.

Platform Assessment Support Authentication Methods
SQL Server on Windows Full support Windows Integrated Authentication, SQL Server Authentication
SQL Server on Linux Full support SQL Server Authentication only
SQL Server on Linux: SQL Server instances running on Linux can be discovered during infrastructure scans and assessed using DMC. However, only SQL Server Authentication is supported for SQL Server on Linux instances. Windows Integrated Authentication requires a Windows domain environment and is not available for SQL Server on Linux.
Assessment Workflow: SQL Server assessment connects over the network to SQL Server instances. The same assessment metrics are collected for SQL Server instances running on both Windows and Linux operating systems, as the assessment queries SQL Server metadata which is identical regardless of platform.

For detailed information about SQL Server assessment requirements and capabilities, see Database Assessment Requirements and SQL Assessment Metrics.
