A minor problem I was faced while upgrading my lab environment to vSphere 6.5 was that during the Migration wizard the following error occurred:
A problem occurred while connecting to the migration assistant on the VUM machine

Migrating to vCenter 6.5: Design decisions and important characteristics/limitations to consider
Even though vSphere 6.5 has been announced and not released yet Since vSphere and vCenter 6.5 are released now, a customer engagement put me into a position to gather much more information about characteristics and limitations within vCenter 6.5.
In the following I will discuss some of the upcoming and current vCenter characteristics that might not be completely aware (are not well documented) within the field /community.
Thanks VMware @Twitter community for helping me out here. Once again I really benefit from this great network out there.
The goal was to define a logical and physical design for the new vCenter release. Within the project we will have two phases
- phase: vCenter 6.0
- phase: vCenter 6.5
We will give the GA release of vCenter 6.5 a minimum time of 3 months to observe its behaviour and production readiness. Since we might require feature from the vCenter 6.0 release we want to design that is ready for an easy transition from 5.5 over 6.0 to 6.5.
However if you ever decide to move on to vSphere or vCenter 6.5. Please check the upgrade sequence here first & check the compatibilities (within VMware’s and 3rd party products).
Current state:
- Windows based vCenter (vCenter 5.5 U2e)
- SQL Server installed on the vCenter Windows

*** Updated (22-04-2016): Links changed for vCenter 6.0U2 release.
There are a lot of great blogs out there about the process of upgrading the vCenter from 5.X to the most current version 6.0U2.
Having done the upgrade now in multiple production environments I try to summarize the general process and potential caveats. The following article is more a general approach and not specifically tied to a certain version. I start with the key facts outcome first. The detailed description where those key facts are extracted from are mentioned afterwards.
