vSphere Compatibility Predictor – fling test

VMware has just released a new fling called vSphere Compatibility Predictoricon-icoIt is basically an upgrade checking tool. Validates if your currently running vSphere 5.5 / 6.0 infrastructure components will work with 6.5 or not.

This Fling scans all PSCs connected to a single
PSC. It will detect the versions of all the vCenter Servers connected to PSCs and all the Solutions connected to vCenter Servers. It will then depict the connectivity in pictorial form.

When you choose the Upgrade View in the Fling, it will show which Solutions are compatible with vCenter Server 6.5. This can help the administrator plan the upgrade in advance.


After accepting the Technical Preview License, the .zip can be downloaded. It contains the VMware-vSphere-Compatibility-Predictor-Setup-1.0.0-20170127.exe, install it on a Windows 2008R2/2012/8.1.



I have tested it with both existing vCenter versions: 5.5 and 6.0. Use the PSC/SSO credentials. (vsphere.local\Administrator). With the default settings you can login into a vCenter 6.0 only – that is using the LDAP port 636. So based on the versions you need the following LDAP ports:

  • vSphere 5.5 SSO: use the port 11712
  • vSphere 6.0 PSC: use the port 636

Otherwise you will get the following error:

Could not able to make the connection to PSC/SSO Ldap Server…


However the same will be displayed, even with wrong user/password, port, IP as well.


After a successful login Accept the thumbprint, then select the site (vCenters and PSCs will be displayed) and press Upgrade View. In our 5.5 example a couple of extensions are compatible with 6.5:

  • vCenter Intelligent Power Plug-in (EATON)
  • vShield Manager
  • VR Management
  • VDP 6.1
