I tested vSphere 6 quite intensively when it was in beta, but I didn’t ever upgrade my lab - basically because I need a stable environment to work on and I wasn’t sure that I could maintain that with the beta.
Now 6 has been GA a while and I have a little bit of time, I have begun the lab upgrade process. You can see a bit more about my lab hardware over on my lab page.
I will be upgrading
vCenter Server Appliance - currently 5.5 update 1
vSphere Update Manager - currently 5.5 update 1
3 HP N54L resource hosts
1 Intel NUC management host
In my lab I run various VMware software suites listed below, although I typically run them in nested environments to keep my lab install relatively clean.
vCloud Director
vRealize Automation
vRealize Orchestrator
NSX
Other considerations:
VSAN - I currently run VSAN 5.5 and will need to upgrade to 6.0
Update Manager - I’d prefer to update my hosts using Update Manager where possible
Certificates - I currently use a Microsoft CA, I’d like to move to the VMCA as a subordinate CA
Drivers - VMware changed the drivers supported in ESXi, some consumer grade drivers are blacklisted
Backup - I use the excellent Veeam Backup and Replication to protect key lab machines, and I know that it doesn’t yet support vSphere 6. That’s a hit I can take in my lab.
