Things to keep in mind if upgrading to vSphere 5.5

If you are a super early adopter there are a few KB articles that you will want to keep an eye on if you are looking to go to vSphere 5.5 already.

Thanks to Marcel @ Lumenate for pointing these out to me… apparently they were on the download page for vSphere 5.5, but who reads the instructions right ?

KB2060511 – Upgrade from vSphere 5.1 to vSphere 5.5 rolls back after importing Lookup Service data (2060511)

KB2060901 – Active Directory authentication fails when vCenter Single Sign-On 5.5 runs on Windows Server 2012 and the AD Domain Controller is also on Windows Server 2012 (2060901)

 

Also if you are upgrading an existing vSphere server you will want to make sure that your SSL certificates are not expired.

ssl

  1. Locate the certificate file (rui.crt) by viewing the contents of the vcsso.properties file (default on Windows is C:\ProgramData\VMware\VMware VirtualCenter\ssl)
  2. Run openssl against the certificate.  On Windows, the program is located in

C:\Program Files\VMware\Infrastructure\Inventory Service\bin\

openssl x509 -in C:\ProgramData\VMware\VMware VirtualCenter\ss\rui.crt -noout -text

  1. Look for the validity dates:

Validity

    Not Before: Nov 15 21:46:40 2012 GMT

    Not After : Nov 14 21:46:41 2022 GMT

And make sure that the “Not After” date is in the future.

Here is an example from my vCenter server, look for the dates about 10 lines down from the top.
