The procedure (untested by me) should be similar to the procedure on the
CentOS Wiki for migration from RHEL to CentOS:
http://wiki.centos.org/HowTos/MigrationGuide

Something like this for i386:

rpm -e --nodeps centos-release centos-release-notes \
  redhat-artwork redhat-logos redhat-menus

rpm -ivh \
http://ftp.scientificlinux.org/linux/scientific/55/i386/SL/sl-release-5.5-1.i386.rpm 


http://ftp.scientificlinux.org/linux/scientific/55/i386/SL/sl-release-notes-5.5-1.noarch.rpm
http://ftp.scientificlinux.org/linux/scientific/55/i386/SL/redhat-artwork-5.0.9-2.SL.2.i386.rpm
http://ftp.scientificlinux.org/linux/scientific/55/i386/SL/redhat-logos-4.9.16-1.SL.6.noarch.rpm
http://ftp.scientificlinux.org/linux/scientific/55/i386/SL/redhat-menus-6.7.8-3.el5.noarch.rpm

(all on one line, or use sequential rpm commands)
