Currently have 2 VMware hosts running ESXI 4.1 with vcenter essentials.  So i am licensed to add a 3rd host, which i currently just bought.  But I also purchased vcenter essentials 5.1 and want to upgrade the other hosts. Can i load esxi 5 on the new host and upgrade vcenter server to 5 and add the vsphere 4 hosts then upgrade them with update manager? or will i have to move the VM's off each host and then upgrade because of the version upgrade?  Oh and they are all local storage hosts.

Thanks!

You can install ESXi 5.1 on your new host, you will need to upgrade your existing vCenter Server from vCenter Server 4.1 to 5.1. Once you have completed this you will be able to add your new ESXi 5.1 server.

and then use Update Manager to update your outdated hosts from ESXi 4.1 to ESXi 5.1.

Whilst doing the Update, the servers will be in maintenance mode.

Make sure you always have a backup of your VMs before any upgrade.

See my EE Article, but also check your old hosts meet the ESXi 5.1 requirements
