I have a condor cluster (V7.0.4) which includes ten execution computers that is 7/24 is busy and I rarely see some of them when they are iddle. I am thinking to gradually upgrade whole the system to version 7.4.4 but I have some questions at the moment.
Is it possible, starting to upgrade any execution machine when it is iddle? I saw somewhere I should start to upgrade with Condor Central Manager first. Is this true?
Can it be a problem different version condor systems in a condor cluster?
Which package best for the smooth upgrade? I am using CentOS 5, I guess I should use Redhat 5 dynamic package, I saw standard Redhat 5 package does not support upgrade option in V 7.4.4 manual. I am thinking compiling all the source code again may cause some other problems or conflicts.
Thank you in advance and Best Regards, Dogan YILMAZ
