Power BI Admin Need to Convert Old Sensitivity Labels to New ones In Mass

[rbrocks]

I am the Power BI administrator for my company. We currently use sensitivity labels for Power BI. However, the security team has decided to migrate to a new list of sensitivity label options that have a label/sub-label structure. 

In planning for this, I am trying to understand if there is a way to do a mass conversion of labels. Specifically I would like to be able to do this conditionally.

i.e. if label = "Public" set as "General/Anyone", if label = "Confidential" set as "Confidential/All Internal Employees"

I am definitely not a PowerShell guru. I have dabbled enough to be dangerous. I have seen the scripts to set and remove labels but I am not sure if this can be done conditionally. 

What is the best way to go about accomplishing this?
