When using the Data Migration Assistant you’ll have an option to export the findings as CSV or JSON.

The following provides a guide to importing the JSON data into a database table for you to review.

Firstly, create a table to hold the information using:

CREATE TABLE DMA_Findings
(
 [Project_Status] nvarchar(128)
,[Project_Name] nvarchar(128)
,[Project_SourcePlatform] nvarchar(128)
,[Project_TargetPlatform] nvarchar(128)
,[ServerInstances_ServerName] nvarchar(128)
,[ServerInstances_Version] nvarchar(128)
,[ServerInstances_Status] nvarchar(128)
,[Databases_ServerName] nvarchar(128)
,[Databases_Name] nvarchar(128)
,[Databases_CompatibilityLevel] nvarchar(128)
,[Databases_SizeMB] decimal (20,2)
,[Databases_Status] nvarchar(128)
,[Databases_ServerVersion] nvarchar(128)
,[Databases_ServerEdition] nvarchar(128)
,[AssessmentRecommendations_CompatibilityLevel] nvarchar(128)
,[AssessmentRecommendations_Category] nvarchar(128)
,[AssessmentRecommendations_Severity] nvarchar(128)
,[AssessmentRecommendations_ChangeCategory] nvarchar(128)
,[AssessmentRecommendations_RuleId] nvarchar(128)
,[AssessmentRecommendations_Title] nvarchar(160)
,[AssessmentRecommendations_Impact] nvarchar(4000)
,[AssessmentRecommendations_Recommendation] nvarchar(4000)
,[AssessmentRecommendations_MoreInfo] nvarchar(4000)
,[ImpactedObjects_Name] nvarchar(128)
,[ImpactedObjects_ObjectType] nvarchar(128)
,[ImpactedObjects_ImpactDetail] nvarchar(4000)
,[ImpactedObjects_SuggestedFixes] nvarchar(4000)
);

Next, import a single DMA json file using:

INSERT INTO DMA_Findings( 
 [Project_Status]
,[Project_Name]
,[Project_SourcePlatform]
,[Project_TargetPlatform]
,[ServerInstances_ServerName]
,[ServerInstances_Version]
,[ServerInstances_Status]
,[Databases_ServerName]
,[Databases_Name]
,[Databases_CompatibilityLevel] 
,[Databases_SizeMB]
,[Databases_Status]
,[Databases_ServerVersion]
,[Databases_ServerEdition]
,[AssessmentRecommendations_CompatibilityLevel]
,[AssessmentRecommendations_Category]
,[AssessmentRecommendations_Severity]
,[AssessmentRecommendations_ChangeCategory]
,[AssessmentRecommendations_RuleId]
,[AssessmentRecommendations_Title]
,[AssessmentRecommendations_Impact]
,[AssessmentRecommendations_Recommendation]
,[AssessmentRecommendations_MoreInfo]
,[ImpactedObjects_Name]
,[ImpactedObjects_ObjectType]
,[ImpactedObjects_ImpactDetail]
,[ImpactedObjects_SuggestedFixes]
)

) AS [Project]

Or, if you have lots of DMA json files you can quickly load them all using the following PowerShell

$dma_json_folder = 'C:\....\' # Location of the the DMA json files
$instance_name = '...' # SQL instance which will contain the findings
$database_destination = '...' # Database on the SQL instance

# Get a list of the audit queries
$dma_json_files = @(Get-ChildItem $dma_json_folder *.json) # Get a list of audit queries

if ($dma_json_files.Length -ne 0) # Proceed as queries to run
{

try 
{
Foreach ($dma_json_file in $dma_json_files) # Cycle through each query
    {
    [string]$json_file = $dma_json_file.BaseName + '.json' # Set output file name

$query = @"

    #
    Write-Host "Processing" $dma_json_folder$json_file
    # Use Invoke-Sqlcmd to extract the information

Now you’ll be able to query the findings:

SELECT * FROM [DMA_Findings];

An example of finding issues for a migration to SQL Server 2017 you could use a query like:

SELECT 
 [Databases_ServerName] AS Instance
,[Databases_ServerEdition] AS InstanceEdition
,[ServerInstances_Version] AS InstanceBuild
,[Project_SourcePlatform] AS SourcePlatform
,[Project_TargetPlatform] AS TargetPlatform
,[Databases_Name] AS DatabaseName
,[Databases_CompatibilityLevel] AS DatabaseCompatibilityLevel
,[AssessmentRecommendations_CompatibilityLevel] AS TargetCompatibilityLevel
,[Databases_SizeMB] AS Database_SizeMB
,[AssessmentRecommendations_Category]
,[AssessmentRecommendations_Severity]
,[AssessmentRecommendations_ChangeCategory]
,[AssessmentRecommendations_RuleId]
,[AssessmentRecommendations_Title]
,[AssessmentRecommendations_Impact]
,[AssessmentRecommendations_Recommendation]
,[AssessmentRecommendations_MoreInfo]
,[ImpactedObjects_Name]
,[ImpactedObjects_ObjectType]
,[ImpactedObjects_ImpactDetail]
FROM [DMA_Findings]
WHERE 1=1
AND [AssessmentRecommendations_CompatibilityLevel] = 'CompatLevel140'
ORDER BY [Databases_ServerName],[Databases_Name],[AssessmentRecommendations_Severity],[AssessmentRecommendations_ChangeCategory];
