[voonxx]

"Processors": [
{
"ProcessorType": "AzureDevOpsPipelineProcessor",
"Enabled": true,
"MigrateBuildPipelines": true,
"MigrateReleasePipelines": true,
"MigrateTaskGroups": true,
"MigrateVariableGroups": true,
"MigrateServiceConnections": false,
"BuildPipelines": null,
"ReleasePipelines": null,
"Enrichers": null,
"SourceName": "PipelineSource",
"TargetName": "PipelineTarget",
"RefName": null,
"RepositoryNameMaps": {
"Awesome Project":"Awesome Project"
}
}
],
