In this article, I will try to explain how to upgrade Single Sign-on. If you did it before from 5.0 to 5.1, it is almost same process. However, there are some differences we have to mention them here.
First of all, admin@system-domain has gone:) new SSO account is "email@example.com"
Besides, there are lots of information can be found in this link as well http://pubs.vmware.com/vsphere-55/index.jsp
Moreover, If you want to get more information about what’s new in Vmware 5.5, this PDF document can help you http://www.vmware.com/files/pdf/vsphere/VMware-vSphere-Platform-Whats-New.pdf
The best improvement is that VMFS supports 64TB now and as you know it used to be 2 TB before.
Let’s start the upgrade. When you open the media, I hope you are familiar with that "Simple and Custom Installation". I have no idea how Simple installation looks like:) I have never clicked on it before.
Custom installation and firstly, SSO installation are recommended.
SSL certificate is not expired let’s continue
As you can see, the installation has found my previous SSO installation and it will be upgraded.
My old version, 5.1, has been caught.
I want to upgrade existing SSO
You should type new password of SSO now, more information this is the link you need; http://pubs.vmware.com/vsphere-55/topic/com.vmware.vsphere.upgrade.doc/GUID-4CEA7F38-F24D-4833-830C-721578D4BA77.html
I leave the default site name.
Done. My installation has been completed successfully.
