witadmin importwitd /?

This command imports a work item type XML definition file into a team project
on a Team Foundation Server.  If a work item type with the same name already
exists, the new work item type definition will overwrite the existing
definition. If the work item type does not already exist, a new work item type
will be created.

Usage: witadmin importwitd /collection:collectionurl [/p:project] /f:filename
[/e:encoding] [/v]

 /collection    Specifies the Team Foundation project collection. Use a fully
                specified URL such as http://servername:8080/tfs/Collection0.
 /p             Specifies the team project in which the new work item type is
                imported.  This is required, except when the validation-only
                option is used.
 /f             Specifies the work item type XML definition file to import.
 /e             Specifies the name of the .NET Framework 2.0 encoding used to
                import the XML file. For example, /e:utf-7 will use Unicode
                (UTF-7) encoding. Encoding is automatically detected whenever
                possible. If the encoding cannot be detected, UTF-8 is used.
 /v             Validates the XML definitions for the work item type, link
                type, or global workflow without importing them.
