Als ehemaliger, langjähriger "COBOLier" und "HOSTy" finde ich die Thematik um "Mainframe Modernisierung" natürlich sehr spannend und vielschichtig. Natürlich sind unsere hauptsächlichen Ansatzpunkte dank/mittels SOA und WebServices, welche hier spannende Möglichkeiten der Integration und Interoperabilität zwischen Mainframe und Microsoft Plattformen ermöglichen. Innerhalb von BizTalk Server 2006 ist u.a. auch die Möglichkeit der Mainframe Integration durch die Mainframe Adapter durch Integration des ehemaligen Host Integration Server HIS, für DB2 integration und Applikationsintegration (MS-initiated und/oder Mainframe-initiated). Viele dieser Informationen finden Sie unter: 
Ganz neu gibt es hierzu die folgenden Mainframe Migration Whitepaper (nur in englischer Sprache):
- Microsoft Operations Framework for Legacy Modernization
- Migrating Mainframe Applications to Windows Server
- Service Orientation and its Role in your connected Systems Strategy
- TPF Legacy Modernization and Why the NeoSort World Record is Important for Mainframe Users

Microsoft Operations Framework for Legacy Modernization

The Microsoft® Operations Framework provides guidance and best practices for more effectively managing an IT environment that is based on Microsoft software. This white paper is designed for organizations that are moving workloads from a mainframe to system running Microsoft technologies.


Migrating Mainframe Applications to Windows Server

Get insight and clarity into the process of legacy modernization, with a focus on application migration. This paper demonstrates the feasibility of incrementally moving workloads off a z/OS Mainframe. The results demonstrate a possible significant cost savings and performance increase associated with mainframe application migration.



Service Orientation and Its Role in Your Connected Systems Strategy

Service orientation is a means for building distributed systems. At its most abstract, service orientation views everything ”from the mainframe application to the printer to the shipping dock clerk to the overnight delivery company” as a service provider. Service providers expose capabilities through interfaces. Service-oriented architecture maps these capabilities and interfaces so they can be orchestrated into processes. The service model is "fractal": the newly formed process is a service itself, exposing a new, aggregated capability.



TPF Legacy Modernization

Read this feasibility study about migrating an IBM mainframe Transaction Processing Facility (TPF) application to Windows Server 2003 R2 running on a Unisys ES7000/one Enterprise Server.  The study includes how-to guidance as well as relative performance data, giving you a first look at how you might re-engineer a TPF application to run on the Windows platform.  The paper was written by Hexaware, in co-operation with the Microsoft Legacy Modernization team.

Why the NeoSort World Record is Important for Mainframe Users

On February 7, 2006, Ordinal Technology and Fujitsu set a new world record for the MinuteSort benchmark in the “Daytona,” or commercial program, category using the NeoSort sort program. NeoSort processed 40 gigabytes of data (400 million 100-byte records) in less than one minute. The sort ran on Fujitsu PRIMEQUEST computers using Fujitsu ETERNUS storage subsystems—hardware that costs a fraction of the cost of today’s mainframe systems. Given the very real challenge of mainframe batch jobs approaching or exceeding the limits of available batch windows, this benchmark proves that companies now have a choice outside of expensive mainframe upgrades.
