Migrating work items to VSTS with custom fields using TFS Integration Platform
If you wish to migrate work items from TFS to VSTS your options are limited. You can of course just pull over work items, without history, using Excel. If you have no work item customisation them OpsHub is an option, but if you have work item customisation then you are going to have to use TFS Integration Platform. And we all know what a lovely experience that is! Note: TFS Integration Platform will cease to be supported by Microsoft at the end of May 2016, this does not mean the tool is going away, just that there will be no support via forums....
