You do not need to keep the statistics. If you simply want to know how many
jobs were handled by the RB, you can run this command:
/opt/condor/bin/condor_history | awk 'n < 0 + $1 { n = 0 + $1 } END { print n }'

Depends on what you want to keep exactly. Probably the only useful data
would sit in the MySQL database, so you would stop the edg-wl-* services
and mysql, tar up /var/lib/mysql and save it somewhere; on the reinstalled RB
you would unpack the tar ball instead of doing the usual MySQL initialization
(assuming the databases on RH73 and SL3 are binary compatible).
