First steps in upgrade from 5.5 to 6.5

Hi all,

Current plan to upgrade is:

ADDED---- I need to upgrade my current vcenter server first to 6.5 yeah?

New ESXi host to add to my current 4 in production.

Build this as 6.5 host

Create a vm on this host to act as my embedded PSC appliance with vCenter server also installed on this VM

Migrate VM's from host 1 to the new 6.5 esxi host.

Upgrade host 1 to 6.5

Migrate the vms back onto the newly upgraded host.

Do this for each old 5.5 host.

I have a DR site which is also 5.5 and will be migrated to 6.5 but I think I can do this after the production upgrade.

Is there anything you would change here?

Thanks for any replies!
