R&S IdPs in the InCommon Federation are currently in the process of migrating to global R&S. Likewise new R&S IdPs will be encouraged to support global R&S as well. More importantly, InCommon will soon begin importing the metadata of R&S IdPs from other federations. In anticipation of these events, existing R&S SP owners should begin to develop a migration strategy for global R&S.
Since all R&S SPs in the InCommon Federation now meet the requirements of the international REFEDS Research & Scholarship Entity Category specification, R&S SPs have a multivalued R&S entity attribute in InCommon metadata. In that sense, all R&S SPs have successfully migrated to global R&S. However, if an R&S SP deployment depends on the R&S entity attribute in IdP metadata, then additional migration steps may be required since the entity attributes in IdP metadata will change as IdPs declare their support for global R&S.
For example, a small number of R&S SPs SP deployments are known to filter IdP metadata such that R&S IdPs are the only IdPs exposed on the SP's discovery interface. Such an SP is dependent upon the R&S entity attribute in IdP metadata.

since IdPs that support global R&S will necessarily carry the latter in their metadata. Indeed, R&S IdPs from other federations will carry the refeds.org R&S tag exclusively.
