Written by jl on March 13th, 2013

Hello everyone

En este y sucesivos artículos os vamos a describir los pasos que hemos seguido para realizar la actualización de vSphere 4.1 a vSphere 5 en un entorno de producción .

The virtual infrastructure that we set is composed of a cluster 3 4.1 ESX servers and virtualized vCenter Server database having an external SQL server 2005. Besides the three ESX servers, two are migrated from previous versions and you have a new installation of version 4

The steps that we have divided the upgrade process were as follows:

Upgrade licenses

Pre requirements

updating vCenter

Reload vSphere client

Update update manager

Actualizar esx host

Reload vmtools

Virtual hardware upgrade

Reload datastores

We will develop each of the parties

Update licenses

The first step we did was update the licenses on the VMware website. To enter this page with our VMware and password, select the licenses to update and generate new licenses 5 version. The store because later we will have to enter into our vCenter server when migrated.


The first thing we looked at was the minimum for 5 version, which are:

- Hardware

  • Bits 2 64 processors or dual-core processor 64 Bits.
  • 3GB Minimum RAM.
  • 1 NIC Gigabit
  • 4GB disco.Se of available additional space required if the vCenter database is installed on the same instance be used servidor.Si SQL Server Express Edition 2008 R2, which is included on the installation media, will require Additional 2GB space available for the installation process.

- Software

  • ServervCenter vCenter Server can only be installed in operating systems 64Bits
  • Windows Server 2003 x64 SP2
  • Windows Server 2003 R2 x64 SP1
  • Windows Server 2008 x64 SP2
  • Windows Server 2008 x64 R2
  • Microsoft Framework. NET 3.5 SP1
  • Microsoft Windows Installer version 4.5 (MSI 4.5). This is only required if you use SQL Server Express 2008 R2.
  • ODBC DSN connection 64Bits for Database
  • The server must have a Web service that uses 80 and 443 ports, which are used by vCenter.
  • The server name must not have more than 15 characters.
  • The vCenter Server server should have role installed Domain Controller Active Directory.
  • You must use a static IP. If you use a dynamic IP with DHCP, ensure that the server name is updated in DNS servers.

- Database

  • IBM DB2 9.5 and 9.7
  • SQL Server Express Edition 2008 R2
  • SQL Server 2005 SP3 up
  • SQL Server 2008 SP1 up
  • SQL Server 2008 R2
  • Oracle 10g R2
  • Oracle 11g

In our case 4.1 vCenter Server is a server-bit Windows Server 64 2003 R2 2GB SP4 with RAM, hard 60GB and SQL Server database 2005 SP4, which meets the requirements for upgrading to version 5.


Select vCenter Host Agent Pre-upgrade Checker and give the Install button


We welcome screen appears and we click Next to continue. In the selection screen database have to select the DSN for the vCenter database, put the user and password to connect and give Next to continue


Standard mode is selected we will check all the host of the virtual infrastructure.


We press the Run button precheck and starts running the check.


After a few minutes we are told that the process is complete, we give next and shows us the check results


In our case we had no error, we give Next to continue and complete the process


After seeing that we meet the requirements we started with the upgrade to continue in the next article
