I have a VCentre server virtual appliance, it's currently on build 5.5.0.30500 Build 4180648 and I want to upgrade to 6.0
I''ve downloaded VMWare-VCSA-all-6.0.0.511256-iso and unpacked.
I've opened the vcsa-setup.html
However I'm having issues trying to get it to run.
I want to do an in place upgrade and so I am selecting upgrade but no matter how often I try root credentials it doesn't autheniticate
If I go back and choose migrate It does authenticate and then asks where I want to store the new VM etc etc.
However i believe thats for migrating a Windows box to a new appliance rather than upgrade the existing appliance.
I ran into this same issue. I found that changing the password (longer and more complex) on the host, seems to have resolved the error.
vCSA upgrade (i.e major version) is always out of place upgrade, which means a new Appliance is deployed and the data from existing/old appliance is migrated to the newly deployed appliance.
For any minor version updates the inplace update is applicable. Differences Between vSphere Upgrades and Updates
please refer to the documentation for upgrading to to vCSA 6.0 from 5.x : About the vCenter Server Appliance Upgrade Process
