The usual process for upgrading is to copy the original 6.0 binaries
to 
name
.old versions and then copy the 6.2 binaries over the 6.0
binaries. The condor_ master will automatically (in about 5 minutes)
notice that new binaries have been installed and exec them. Please be sure
to upgrade the configuration files to match the 6.2 version and pay attention
to copying over your site's specific policy to the new configuration file. Some
macros and their meanings have changed and need to be addressed in the
upgrade. You may find them in section 3.6.10 of the
manual.
One special note: You must relink your 6.0 standard universe jobs with the 6.2 supplied libraries. Backward compatibility to 6.0 from 6.2 had been intentionally broken because of an evolution of features that the standard universe now supports.
If you have any questions that are not listed in this FAQ, try looking through the rest of the manual. If you still can't find an answer, feel free to contact us at condor-admin@cs.wisc.edu.
