Export vcenter roles (privileges)


In this post I will be showing how to export roles. and can be imported to another vCenter. This is completely dedicated to exporting roles only, they are exported to specified folder with .role extension. As you can see I have multiple roles created, some are by default created roles, my script skip those roles and only backup User created roles.
When you edit one of the role you will see information some thing like this, these are called roles privileges. Each privilege has some meaning ful name, ie inside alarms there is acknowledge alarm rights.
Here is my script that can pull all this information and keeps in .role file. Copy paste this script and keep it in ps1 file.
  <#

Open vmwere vsphere powercli,  Make sure your execution policy is set to remote singed or something that can execute script. Mine is unrestricted, I only run script created by me only.
Connect to old vcenter server using Connect-VIServer command.
Once you are connected. time to execute command, I have saved my script under c:\script. and this is how I run that script with dot sourcing. Once you run ps1 file you can see on the screen what is happening in yellow.
All the roles file are stored on the c:\temp, now you can copy paste these roles in zip file and ready to be used on other vcenter for importing.
You can open role file in notepad and the view is as below. This is how exported vcenter role file looks like, in my next blog i am going to use same file and export privileges to another vCenter.
