I have inherited the job of system administration of the LONCAPA system
in the Physics Department at the University of South Carolina
(domain:sc). We have 3 physical servers, one library, and 2 access.
All of the systems are running CentOS 5.5 and LONCAPA 2.9.1-2010112008.
I would like to upgrade these. Here are some of the questions I have...
Should I upgrade the OS first and then LONCAPA? From what I have read,
I could install the latest CentOS from scratch on the access servers and
then the latest LONCAPA. Then I would upgrade the library server OS
after backing it up, then upgrade LONCAPA.
Do all the servers need to be done at the same time? Can I "practice"
on one of the access servers to get my feet wet, then do the other
access server, then the library server? This may go over multiple days.
Should I wait until we are not using the system (mid to late December)
to attempt this.
