Upgrading to ESXi 5.0 using Dell Customized VMware ESXi images
Page | 6
Migration from vSphere 4.x to vSphere 5.x
When upgrading to ESXi 5.0, an important factor to be considered, is the difference
in the image contents. You are bound to see some warning/error messages during the
migration process due to the change in the image contents between 4.x and 5.0. Here are
some of the scenarios you may come across during migration from 4.x to 5.0
• Scenario 1: Migration from VMware provided ESXi 4.x image to VMware provided
ESXi 5.0
To upgrade from VMware provided ESXi 4.x to VMware provided ESXi5.0, you will
come across an upgrade/install window as shown below (Refer Fig1). This is a straight
forward scenario where you see 3 options in which ‘Upgrade ESXi, Preserve VMFS datastore’
needs to be used for upgrade.

Update1 to VMware provided ESXi 5.0.
• Scenario 2: Migration from VMware provided ESX 4.x Classic image to VMware
provided / Dell Customized ESXi 5.0
In this case there is a slight change in the term which is used while upgrading from a
classic 4.x branch to VMware provided / Dell Customized VMware ESXi 5.0. Instead of
‘Upgrade ESXi, preserve VMFS datastore’, it does show ‘Migrate ESX, preserve VMFS
datastore’. The important point to be considered here is that the COS (Console Operating
System) available in 4.x branch will be removed after migrating to ESXi 5.0. All applications
(Including Dell OpenManage) installed on classic 4.x will be removed during migration.
Hence, prior to proceeding with migration, make sure to backup the required data in COS.
The OpenManage software installed on COS needs to be reinstalled with the package
supported for ESXi 5.0.
