ERP 6 EHP4,BW 2004s and DMS/TREX Heterogeneous System Copy

Good Afternoon,

This will be my first time doing any System Copy and i will be very gratefull with all the help you can give me on this matter.

I need to plan a execute the system copy of at least three systems on my company. The landscape comprises the following systems:

• SAP ERP 6 EHP4 (Business Suite) - Development, Test and Production Systems
  • Components: SAP ECC 6.0 (Non Unicode) - Kernel 721 Patch 132
  • Database: MSSQL 10.50.5200 (2008 R2 as far as i know)
  • Windows 2003 R2 SP1 (x64)

• SAP BW - Development and Production Systems
  • Components: SAP NetWeaver 2004s - Kernel 721 Patch 134
  • Database: MSSQL 10.50.5200 (2008 R2 as far as i know)
  • Windows 2003 R2 SP1 (x64)

• SAP DMS/TREX - Development, Test (in the same server as far as i understood) and Production System
  • First time ever i have contact with this system don't know much about it even it's concept
  • Components: ???
  • Database: My Information file says SAPDB 7.6 but as far as i know this should be MAXDB 7.6
  • Operating System: Windows 2003 R2 SP1 (x86)

The objective here is to migrate these systems to new servers in the datacenter infrastructure. The new operating systems will be Windows 2008 (don't know the versions yet), and new MSSQL versions.

So, this is a Heterogeneous system copy with the scenario of migrate to a different operating system, and a new database version. I'm checking System Copy and Migration in order to understand the process better.

For now, my idea is to use SAP tools to do this the following way:

1. Preparation (Includes reading docs and download software, if not already present, in source system and download software for the target system)
2. Export the Database (DB-Independent)
3. Transfer the DB "Dump" (Export) to new Server
4. Install DB and SAP System with software in Target System
5. Import the DB "Dump" (Export) to the System with SAP Tools
6. Follow-Up Activities

So this is my idea from a Macro point of view of tasks.

1. Am i missing something here?
2. Which tools are available for this kind of process and which ones you consider the best to use in each system copy, should i use Software Provisioning Manager 1.0 (i don't think i can use it for BW, nor DMS/TREX)?
3. In this particular situation, how would you approach and execute this?

Those are my doubts for now, and all considerations you may have are very welcome. i'm sure more doubts will arise with more doc reading,and i'll keep posting.

All the answers with help will be rewarded of course.

Best Regards,

Pedro Gaspar
