Users are experiencing performance issue when updating their database hosted on a virtual machine. The administrator determines that I/O is high across all HBAs on the ESXi host containing the virtual machine.
What actions will most likely correct the issue without significantly impacting other users?

A virtual machine, VM21, will be migrated between two ESXi 5.x hosts, labeled ESXi01 and ESXi02. Each host has two vSphere Standard Switches (vSS), configured as follows:

1. vSwitch0 has a port group labeled management and a port group labeled vMotion.
2. The management port group contains a vmkernel port tagged for management traffic.
3. The vMotion port group contains a vmkernel port tagged for vMotion traffic.
4. vSwitch0 on ESX01 has an uplink attached to the 10.1.30.0/24 network.
5. vSwitch0 on ESX02 has an uplink connected to the 10.1.30.0/24 network.
6. Each host has a vSwitch 1 with a production port group used by virtual machine traffic.
7. Each vSwitch 1 has an uplink attached to the 10.1.40.0/24

What is true about migrating VH21 to the new host?
