I had this question after viewing VCenter migration steps and caveats from Windows VCenter to Linux appliance 6.0U2 ?
Can i just perform the inline upgrade on my existing Windows VCenter 5.5 Update 3 to the latest or probably the last edition of Windows VCenter using the below: https://my.vmware.com/group/vmware/details?productId=491&rPId=12931&downloadGroup=VC60U2#product_downloads
Would that be as easy as Next-Next-Finish simple upgrade ?
I ask this because I wanted to join new ESXi 6.0 hardware to the current vSphere 5.5 U3 environment but not sure if the newer ESXi can be managed by older VCenter.
Another question is that:
Existing Vcenter 5.5 U3 is running as Standard VCenter and all of the ESXi hosts 5.1 and 5.5 running with vSphere Enterprise Plus License
. Can I join 3x ESXi 6.0U2 that is running as vSphere Essentials Plus
to the VCenter 5.5 U3 Standard ?
