hiho 
I recently migrated my test environment to another vCenter becuase we had some problems with the test environment.
we had Vra set up and running in the first vcenter, and then we moved our (Virtual)hosts into a new vCenter.
everything seems to be working except that the iaas-service not getting registered, this results in us getting a ERROR 404 when logging into our vra tenant
All the services on the iaas virtual machine that should be running are running, and from that VM we can reach the vra appliance and the sql server.
we reconfigured SSO with the new URL to identity appliance and that reports connected.
What i'm looking for is the next step in troubleshooting this, is there any other places we would have to change the URL to vcenter?
our first vCenter was version 5.5u2 and the new one is 6.0, does that have any inpact on where to look for errors?
this is how it looks in the vra applieance manager:
and sso:
and here is the service list of the iaas VM:
