vSphere 5.5 upgrade to 6.0 Update 2.0

Thanks Andrew.
Quick question,I have put steps in order what i am planning to

Step1: will be to turn off all the VMs,

Step2: will be to put the site under maintenance mode,

Step3: would be upgrade the vCentre first from the commands you mentioned,

Step4:would be to follow your procedure on "https://www.experts-exchange.com/articles/18959/HOW-TO-Upgrade-from-vCenter-Server-5-5-to-6-0.html "

Step5: https://www.experts-exchange.com/articles/18919/HOW-TO-Upgrade-from-vCenter-Server-Appliance-VCSA-5-5-to-6-0.html (Would the license will get transferred automatically?)

Step6: https://www.experts-exchange.com/articles/18819/HOW-TO-Upgrade-VMware-ESXi-5-5-to-ESXi-6-0-in-5-easy-steps.html

Is step 6 required?

Does that sound right? Did i miss anything?

vCenter should be updated as step 1, to reduce overall downtime.

You must START by upgrading vCenter Server first if you use it! That's the first thing you MUST do!

You must have new LICENSES for 6.0. 5.5 licenses will NOT work.

Step4/Step5 are vCenter Upgrades.

Step 6 is ESXi upgrades.

Thanks Andrew, the order of the upgrade is all good?

Yes, BUT do vCenter Server FIRST! no need to shutdown ALL VMs, and Maintenance Mode for vCenter Server upgrade.

and also get your licenses before you start!

I am getting this error during upgrade....

Error: unsupported database driver

c:\Windows\system32\sqlncli.dll

Resolution: verify you're using vCenter Server with supported driver

Your SQL database is not supported by the upgrade for vCenter Server 6.0.

Thanks, in that article there is no solution on how to fix this issue :-(

Upgrade SQL, delete the DSN. Re-install and Upgrade.

Thanks Andrew, i have done the required changes.

Now its waiting on the attached screenshot for 4-5 hours, should i cancel it? or wait for it.

4-5 hours seems extreme! time to cancel, it states a few minutes.

I tried again, getting the same SQL error as i posted above :-(

I will repeat the process to upgrade SQL.

Thanks Andrew, we got involved a tech from VMWARE, and he was trying to check the properties for VCDB in SQL, he gave up, he tried to log in to SQL through sa, admin, and SDE account. none of them can show who is the owner of VCDB DB. Have you seen the attached error or know how it can be fixed?

Yes, and when we have this much trouble with abandoned the Upgrade, and complete a new vCenter Server installation.

kool will do as you said, do i have to migrate anything from old server to new one?

No. Look at using the appliance, and to help you, disassociate the current hosts with vCenter Server.

Thanks Andrew, last question :-) any article on how to disassociate the hosts with vCenter server?

Log directly to ESXi using the client, and click Disassociate with vCenter Server on the Summary page.
