Important documentation regarding the use of X.509 certificates in Federation metadata has been updated and expanded. In particular, a new document on certificate migration within the InCommon Federation describes how to systematically replace an old certificate with a new certificate in metadata. This is especially useful in the case of expired certificates, which often cause interoperability issues with other software. InCommon recommends that you plan ahead and migrate to
an unexpired certificate well ahead of your certificate's expiration date.
This information is part of InCommon's Technical Guide, located on the InCommon Collaborate wiki, that also includes such information as software configuration, technical profiles, and updates to InCommon operations.
