You are planning a vSphere 4.1 to 5.0 upgrade. The production datastores are 6 TB. Each datastore consist of thee extents of 2 TB and is currently 65% full. The operations team would like to keep the system as close to the current configuration as possible. The upgrade process also requires as little service impact as possible. In addition, you wish to use storage I/O control as soon as possible, due to a mission-critical business application requirement. Which of the following would be the correct approach?
A. Create a new VMFS 5 datastore of 6 TB
Enable storage I/O control
Migrate the VMs using storage vMotion
Configure storage I/O shares as required
B. Upgrade the VMFS 3 datastore
Enable storage I/O control
Configure storage I/O shares as required
