Hello fellow Spiceheads,

I have a site that I am in the process of upgrading the Vcenter VCSA 6.5U2 to VCSA 7.0U3. I tried this over the weekend without success.

I am attempting an Upgrade vs a Migration. I am following the process using the link below

Everything starts out fine until after step 7. I receive an initial message about a security certificate issue and it offers the SHA thumb prints for 2 certificates. I enter the yes, accept these certificates and then it starts processing and stops with an error log message.

I have validated the passwords individually for both the Vcenter and the Host and well as the Vcenter root password.

The error is that the process is unable to authenticate with the host. The exact error is error: sourcePrecheck: error in getting source Info: ServerFaultCode: Failed to authenticate with the guest operating system using the supplied credentials.

Has anyone seen this before and found a work around. I am also opening a ticket with VMware but wanted to see if anyone here has experience with this issue as well.

Any help appreciated.

Thank You!

If you don’t have a large complex setup, it’s likely quicker just to build a new one and move your hosts over, noting the storage and networks you need.

If you are running the migration from a different subnet to that of your VCSA and/or your new one, you may also need to change the port groups to allow promiscuous mode.

Be sure your VCSA is 7.0U3 and no patch releases, as it may not support your EWSXi 6.5 hosts.

If it’s saying password is incorrect, please confirm it is valid by logging in to VCSA:5480 and ESXi respectively with their passwords.

This could be due to the root password being expired. You will need to change the root password.

To reset the password follow the steps below:

Connect to the source vCenter using SSH.

Execute “chage -l root” command to check if the root password has expired

Change the password using the command “passwd”

Initiate the upgrade again

Thanks ShaneWilliamson, that was exactly what I needed to do to get the upgrade moving.

Passwords on default / OOTB accounts in VM appliances eventually expire and it can cause huge headaches like this. Perhaps not best-practice for security, but I just set mine to never expire so I avoid this whole thing (lab environment, though):
