I'm currently reading through the guide and how to upgrade vCenter Server in Chapter 4 of "vSphere Upgrade: vSphere 5.1."
I'm reading other documents such as best practices, etc. and taking copious notes.
Before I get started, I just wanted to lay-out my environment and ask the community if there are any "gotchas" that I need to be aware of.
I have 2 VMware ESXi Essentials hosts in production, running approx. 50 VMs. One of these is 4.0 and the other is 4.1 Update 1.
I am adding a 3rd host. It will be 5.1.
I am now upgrading my vCenter Server install from 4.1 to 5.1. I also run Veeam and recently updated it to 6.5 per Veeam's recommendation.
After running the "vCenter Host Agent Pre-Upgrade Checker," until everything is updated and passes, is there anything left to do besides run the DVD to upgrade vCenter Server?
My current vCenter Server 4.1 is installed in a 64bit Windows 2008 R2 Standard server vm and runs the SQL Server Express that came with 4.1 I believe.
Thank you,
