At 11pm GMT last night, we put our new Windows Server 2008 R2 cluster into production.\u00a0 We use Virtual Machine Manager (VMM) 2008 R2 to migrate the first machines from our W2008 cluster to the W2008 R2 cluster.\u00a0 We\u2019re a hosting company so we had to do this at times that suited the customers and we had to do some other steps so their \u201csites\u201d were not unresponsive.<\/p>\n
The VMM moves ran pretty well.\u00a0 One of the machines failed to install the updated IC\u2019s in the job so I reran the IC upgrade by itself.\u00a0 Once each machine moved over to the new cluster (on the CSV) I tested live migration.\u00a0 These were all web servers so the tests were simple \u2013 RDP into the machines via VPN, run a continuous ping from them to their respective default gateways and refresh websites from a browser while the migration was running.\u00a0 RDP didn\u2019t have a disconnect or a hitch, ping didn\u2019t miss a packet and none of the IE refreshes failed.\u00a0 All worked well.<\/p>\n
The real test would be what would happen over night.\u00a0 As usual, the phone stayed close by.\u00a0 My real dread was seeing my inbox when I would come down in the morning.\u00a0 Would it be full of alerts from OpsMgr?\u00a0 We use OpsMgr 2007 R2 to monitor server hardware, virtualisation, operating systems, services, applications and to do some client side perspective monitoring of websites.\u00a0 One of the migrated customers is a web developer\/hoster with a lot of sites.\u00a0 They\u2019ve identified a decent number of critical sites for client perspective monitoring.\u00a0 Any problems at all over night and Outlook would be a scary proposition.<\/p>\n
I might have only gotten to sleep at 02:00 but I was awake at 07:30.\u00a0 I came downstairs and powered up my work laptop.\u00a0 Outlook had \u2026 no new mails.\u00a0 Phew, what a relief!\u00a0 I was very confident after a rigorous test program but you never know when you make a big change.\u00a0 I fell good now about completing this migration, hopefully next week.<\/p>\n","protected":false},"excerpt":{"rendered":"
