Re: [condor-users] Can I replace the Condor server in a live pool ?

Yes, there will be no problems, you just won't start up new jobs while 
there isn't a central manager.

As long as the name/ip hasn't changed, you won't have a problem. Otherwise, 
you'll need to edit your configuration file(s) to point at the new server 
and do a condor_reconfig on the nodes.

You will probably notice that it will take about five minute for 
"condor_status" to regain all of knowledge it used to have about the pool, 
but it will happen automatically.

Running jobs will continue running. Queued jobs will remain queued. If jobs 
are interrupted during the outage, they will be queued then restarted when 
the central manager returns.

There is no need to do anything like that.
