At long last we have the Data Warehouse move documentation! This is a follow up blog post to the one about How to move the Service Manager Database .
The documentation how to do this will be added to the TechNet library once it has been formatted but you can get a copy of it here now as an attachment to this blog post.
Note: this document is for 2012 so if you need to move your 2010 DW DBs - upgrade to 2012 first and then move.
Please provide us any feedback on this in the comments below.
A special thanks to Manoj Parvathaneni (Senior Support Escalation Engineer) for going to extra effort to get this documented
Update: July 3rd 2012 - attached 2010 and 2012 versions of the DW move document.
