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

[Patrick Townsend <patrick.townsend@xxxxxxxxxxxxx>]

Hi

Is it possible to replace the Condor server in a running pool?

Condor version 6.4.7 manual, section 7.6, page 266 says
---------------------------------------------
What happens if the central manager crashes? If the central manager 
crashes, jobs that are already running will continue to run unaffected. 
Queued jobs will remain in the queue unharmed, but can not begin running 
until the central manager is restarted and begins matchmaking again. 
Nothing special needs to be done after the central manager is brought back 
online.
---------------------------------------------

Does this also apply for slipping in a replacement server at the same 
network address?

Current server = WinXP Pro, old hardware.
Replacement server = Win 2003 Standard Server, new hardware.
All server tasks are performed by one server, no checkpointing servers on 
aything fancy.

Just by replacing the old server with the new will the nodes - both 
submitting and executing - cope, or do I need to refig them? Will running 
jobs, queued jobs, etc continue as normal, or recover when the matchmaking 
starts again

Or do I need to copy some server data files across to ensure continued 
service?

	best regards
		Patrick.
