Validation of work item fileds if all of them exist in target work item type

I migrated backlog of one of our projects from on-premise TFS to Azure DevOps. After migration, I noticed, that the source process was modified and some fields were added to work items. Because these fields did not exist in target work item, they were not migrated.

I would like to have som validation of work items, so the process notifies me if something is missing in target work item. I can then decide what to do with it. This feature should support.

• Respect work item type mapping. So if Product backlog item in source is mapped to User story in target, the check must be made between these two work item types.
• Allow to configure field mapping between source and target. So field A in source will be mapped to field B in target. Then existence of B is checked in target. This may seem similar to what FieldMappingTool does. But in case of validation, no data are moved from source to target and this mapping is only for purposes of checking the existence of fields.
• Allow to configure that the source field is unnecessary and so it will not be checked in target. This is basically to explicitly state current behavior, that this field will not be migrated.
• Log all missing fields in target, so the user can decide what to do with them.

I have already implemented it locally, because I need it. So my question is if it is something that could be incorporated in migration tool. If yes, I will make a pull request.

Yes.

Its been on my backog for a while and I used to have a powershell that did this. I'm planning on a new command called "discovery" that wouldoutpost all of this info. But its a dream right now...

OK. I made a PR #2885. If it does not suit you, you can just close it. :)
