While Phil's guide is a very good one for C5; however, the OP is asking about EL6, not 5.  EL5 doesn't have 'yum distro-sync' available; this is a seriously handy tool for this kind of migration.  EL6 does have 'yum distro-sync' available.

There's a thread in the Scientific Linux Users mailing list on a similar topic; grep the archives for the subject "How to migrate yum installed on RHEL 6 to update from SL6 repository?" to get more information, especially on the need to replace all the upstream binary packages, not just the logos and the repository configs.
