Issue with field mapping from source to target.

[soodgautam]

I'm trying to migrate the bug work item with field "access code" to the bug work item with field "story point". Its migrating the work item but its not moving the access code field from source to the story point field in target. Please advise, thanks so much! Attached my config file below.

It looks like you are trying to use the new fieldmap setup from v16 for a v15 run. Let me see if I can get a cut of the old docs for you....

OK, you can get the old version of the docs on https://nkdagility.com/learn/azure-devops-migration-tools/docs/v15.2.0/

You want the https://nkdagility.com/learn/azure-devops-migration-tools/docs/v15.2.0/Reference/v1/FieldMaps/FieldtoFieldMapConfig/ which looks like:

{
  "$type": "FieldtoFieldMapConfig",
  "WorkItemTypeName": "*",
  "sourceField": "System.StackRank",
  "targetField": "System.Rank",
  "defaultValue": "1000"
}

It also does not go in MigrationTools:CommonTools:FieldMappingTool:FieldMaps as this is all v16 stuff.... it goes in FieldMaps which you can find a sample of on https://nkdagility.com/learn/azure-devops-migration-tools/docs/v15.2.0/Reference/v1/
