We are in the process of upgrading our current vCenter and ESXi Hosts to 5.1 Update 2 from 5.0. We have the vCenter on one server and the SQL on another server. I have been searching the VMWare KB articles and from what i can see we need to:
1. Install SSO
2. Install Inventory Service
3. Upgrade vCenter
4. Upgrade ESXi Hosts
A couple areas where i am confused are:
1. Before SSO Install we need to create a database. I see THIS
KB article and I am assuming under prerequisites I am doing this on my VM SQL server? Also, it's confusing whether or not i create the RSA_USER and RSA_DBA or if i let the installer do it.
2. I will have the SSO, Inventory and vCenter on one server. We have about 14 hosts and 300 VM's. Other than the requirements listed on the KB article should i be aware of anything else? All the product upgrade docs go to 5.5 so I'm not sure what is valid. I would imagine several things were changed from 5.1 to 5.5
3. When upgrading the ESXi hosts should i be aware of anything? The KB article seems pretty straight forward.
any other advice upgrading from 5.0 to 5.1 Update 2 would be greatly appreciated.
