EV 7.5 SP3 - EV 8.0 SP4 Cluster Upgrade

Hi All, I am looking into upgrading two EV Active/Passive clusters to 8.0 SP4 from 7.5 SP3. I have been looking at the upgrade notes for such a configuration and it seem straight forward enough. The confusion I am getting though is with regards to the second EV cluster. The notes only seem to provide instructions for a single cluster. So I'm wondering when I start the services on the second cluster. The upgrade guides are very careful to separate the instructions for single server and multi server in non clustered configurations. If someone could please point in the correct direction with the steps required to perform this upgrade I'd be very grateful. Kind Regards, Chris Colden

The services on the second cluster should be brought up after making sure that the first cluster was upgraded successfully.
(Directory upgraded, Storage upgraded and so on)

My 2 node cluster upgrade method is as follows:

1. Stop the services on active node
2. Pause the cluster
3. Upgrade binaries on both nodes
4. Bring services up on Active node to update database Schema's
5. Resume cluster
6. Test failover
7. Test Failback

That works for me :)

I'm just about to do a 4 node cluster.
My approach is roughly

stop all task services
check MSMQ queues are empty
Put EV in read only
Stop all other EV services
Stop IIS and all MMC on all nodes
Ugrade server where directory server instance is active
Upgrade all other cluster nodes
Start directory service on directory server instance
Get 8575 in EV Event log
Start admin service on all other EV instances
Run configuration wizard
start Storage services
wait for event s to confirm database schema upgrade
Start other EV services on all instances
Take EV out of read only
