An Azure Files assessment in Azure Migrate helps you evaluate the readiness, cost, and suitability of migrating on-premises file shares to Azure Files. The assessment analyzes discovered file shares and provides recommendations to support your migration planning.
This article explains how to create Azure Files assessments for file shares hosted on Windows and Linux servers. For details information on general Azure Migrate assessment concepts, see assessment overview.
To quickly migrate your on-premises file shares to Azure, create an Azure Files assessment to check readiness, cost, and get migration advice for your workloads.
Note
All assessments created with Azure Migrate are point‑in‑time snapshots. Assessment results can change based on aggregated server performance data or changes in the source environment configuration.
Prerequisites
Before you create an Azure File assessment, ensure that
- Your on-premises servers, and file shares hosted on these VMs are discovered.
- You can view all the servers and file shares in the All inventory and Infrastructure tab. For more information about prerequisites, see Prerequisites for assessments.
After discovery, decide whether you want to create:
- An As-is on-premises assessment, or
- A Performance-based assessment. Check Performance vs. As-is on-premises assessments for more details.
Note
Azure Migrate doesn’t support file share discovery and TCO assessment on Windows Server 2008 R2. This limitation exists because the operating system lacks the required PowerShell capabilities and system APIs needed to discover file shares and collect assessment data.
Create an assessment
To create an assessment, follow these steps:
In the Azure Migrate portal, select Infrastructure and then select file shares.
Select the file shares you want to assess.
Apply column-based filters or custom tag–based filters to identify and add file shares to the assessment scope.
After selecting the required file shares, select Create assessment.
Provide a friendly name for the assessment.
Review the query used to select the fileshares and verify the number of fileshares added.
(Optional) To add more fileshares to the assessment, select Add workloads.
After the assessment scope is complete, select Next.
Note
For accurate calculations, servers hosting the selected fileshares and other colocated fileshares will be automatically added to the assessment scope.
Select Next to move to the Azure Files–specific assessment properties.
Select Edit defaults to review and customize Azure Files–specific settings.
Select Save after updating any settings.
On the Review + create assessment page, review the assessment details, and then select Create Assessment to run the assessment.
After the assessment is created, view it under Decide and plan > Assessments > Workloads
