If you’re working in the cloud, then you’ve probably had a client or two request that you enable Rights Management Services. This is a fairly common task and in a Microsoft Azure cloud scenario or Office 365 scenario fairly simple to enable.
If however you’re working a hybrid configuration or with an organization that’s moving all of their core collaboration services into Office 365 and want to leverage the RMS configuration they’d already setup on-premises to make use of Azure RMS, things get a little more complicated.
Microsoft has put together an Azure Rights Management Services Migration Guidance available through the Microsoft Download Center here – http://www.microsoft.com/en-us/download/details.aspx?id=45505.
The online of this document actually seems to be a little more readable available here Migrating from AD RMS to Azure Rights Management.
Migration scripts that are included in the download from the download center are also available from the online article in Step 5 that point to the Azure Rights Management Administration Tool.
