Upgrading vCops 5.6 to 5.7

With the recent release of VMware vCenter Operation Manager 5.7 and having just recently installed version 5.6 I thought I'd upgrade since it was still going through the "collecting data" phase.  As mentioned, I'm currently using version 5.6:

I've downloaded the 5.7 .pak file which can be used to upgrade from 5.0.0, or 5.0.1, or 5.0.2, or 5.0.3, or 5.6.0 to 5.7.0.  To upgrade simple browse the to the UI vApp VM with the following URL and login with your details:

https://UI_vApp_VM_IP Address/admin/

Check to ensure all the services have started successfully:

Once the core services have started the appliance will be at version 5.7  To verify this check the status tab in the admin console:

Log into vCenter and check the plugins to ensure they are now using version 5.7:
