With the release comes the challenge to upgrade your existing installation.
However, there are a few caveats:
- vSphere 5 is the first version which comes in a ESXi version ONLY! ESXi 5 is available in an embedded or installable version. If you’re running ESX 3.x or 4.x you should do a clean installation. You can find more information here.;
- VMware changed their licensing method. Familiarize yourself with this and check if you need to upgrade/extend your licenses. You can find more information here.
Because I run a VMware vSphere 4.1 environment, this is a upgrade from vSphere 4.1 to 5.
The upgrade is a straight forward five step process.
