The FAQ document attached to this blog is the cumulative knowledge gained from hundreds of customers that have moved off UNIX/Oracle and DB2 to Windows and SQL Server in recent years.
In this document a large number of recommendations, tools, tips and common errors are documented. It is recommended to read this document before performing an OS/DB migration to Windows + SQL Server.
The latest version of the OS/DB Migration FAQ includes some updates including:
Customers are increasingly moving large SAP systems in the 5-10TB range to Azure. This

With powerful new VMs, Accelerated Networking and Premium Storage it is now possible to import even huge size SAP databases on Azure
Based on experience from recent migrations we recommend using SQL Server 2014 SP2 CU2 or SQL 2016 SP1 (as at November 2016). It is generally recommended to use the latest Service Pack and Cumulative update
A future blog will cover specific recommendations for BW migrations. Some changes have been made to improve import performance on BW fact tables and other general recommendations. These will appear in a blog shortly
