Hello everyone

In this article we will continue with the upgrade to vSphere vSphere 4.1 5, and specifically will address the vCenter upgrade part step by step.

VCenter Update

1.- Backup database

First we make a backup of the database for what first stop vCenter services









We go to SQL Server and SQL Server Management Studio do the backup of the database
















2.- Backup ssl certificates

Secondly we backup the vCenter SSL certificates found in C: \ Documents and Settings \ All Users \ Application Data \ VMware \ VMware VirtualCenter and you have to copy the folder SSL

Furthermore, as we discussed in the previous article the vCenter is a virtual server and make a clone snapshot.


3. We update the vCenter

In the run vCenter Server installation package, select the option and click Install vCenter Server













The installation program starts and select the installation language which in our case will be English and click OK








We arrived at the welcome screen of the installation that tells us that there is a previous version installed and will be updated to version 5.














We accept the license



























On the next screen we enter the data of our organization, and we can get the license vCenter 5 or if we can not have it left blank and have a valid evaluation license for 60 days.














We have detected that the DSN configured and all we have to enter the user name and password to connect to the database















On the next screen informs us that the plugins you have installed on the server are not compatible and we'll have to reinstall them once the server upgrade.







At this point we have the option to upgrade the vCenter database exists or not. In our case we select the option to update














We select the following option to automatically update the agents on ESX hosts vCenter Infrastructure














Enter the data of the account you want the services to run














We can select the installation directories, we leave the default routes














In this screen you can modify the ports that will use vCenter. We let them default and are following













As in the previous screen for the inventory service














In this step we select the option Small as we have less than 100 Host














And finally press the Install button and start updating vCenter




























In our case the upgrade cost about 20 minutes and had no error with what at first seems to be done correctly.















The next step is to connect to the vCenter with the vClient but it is necessary to install / upgrade the client version 5, and this will be discussed in the following article
