This is a post, to support
Install a new VERSION of vCenter Server for Windows, and NOT an Upgrade.
A client, decided they wanted to update ESXi hosts to ESXi-5.5.0-20160804001-standard (Build 4179633), what is important, is ANY ESXi build after ESXi-5.5.0-20151204001-standard (Build 3248547) Update 3b
MUST NOW be managed by at least vCenter Server Update 3b or later.
The client currently has
vCenter Server 5.5 Update 2b, and ESXi 5.5 Update 2b Hosts.
All was upgraded correctly to
vCenter Server 5.5 Update 3b 5.5 U3b
Build - 3252642
and then all hosts were upgraded to builds
ESXi-5.5.0-20160804001-standard (Build 4179633)
ALL WORKING perfectly....BUT the client wanted to update to the current version of.... vCenter Server for Windows...
vCenter Server 5.5 Update 3e
and this is where it all went WRONG.
SSO installed and upgraded fine, Web Client all installed and upgraded fine.
Inventory Service fails to install..... ....
Client does NOT want to re-install a NEW version of 3e, and lose historical data and performance.... does not want to upgrade to vCenter 6.0 for Windows or Appliance...
SO we had to escalate to VMware Support....
and currently, they've been looking for 3 hours, and not come up with a solution, other than re-install a new version of 3e, 6.0 as the upgrade will not work!!!!
So......I'll post a fix when there is one!
At present the client cannot move onto vCenter Server 6.0, because of impacts or vCloud, SRM and NetApp...
