A new version of vCenter Server 5.5 was released today. A complete list of included fixes/updates can be found here (short version) and the complete release notes can be found here. You can download the new version here.
I have had some problems when updating both production and test/development environments and most of the problems i have faced seems to have been fixed in this release, e.g:
- Attempts to upgrade vCenter Single Sign-On (SSO) 5.1 Update 1 to version 5.5 might fail with error code 1603
- Unable to change the vCenter SSO administrator password on Windows in the vSphere Web Client after you upgrade to vCenter Server 5.5 or VCSA 5.
- Attempts to search the inventory in vCenter Server using vSphere Web Client with proper permissions might fail to return any results
My latest SSO upgrade problem was fixed by following this KB
Hopefully this new release will save me some troubleshooting time in the near future because i really like the 5.5 release of vSphere.
