vCenter Server Migration

Hi Folks,

I want to migrate my existing vCenter 5.1 to vCenter6.

I have deployed the VCSA 6 appliance and configured it.

The next task is to create/copy folder structure ( virtual datacenters, blue folder,etc ) with roles and permissions from old VC server to new one.

I found some PowerCLI scripts, most of them are talking about copying roles and permissions but not about the folder structure creation.

I have round 150 datacenters in my old vCenter server.

Is there any simplest way to accomplish this?

Please Suggest.

Thanks in Advance.
