Migration from Sun to HP Unix to Windows

Question

Hi ,
There is hardware and OS migration activity is scheduled in my current project. To give you the detail, BI system will be migrated from SUN to HP servers and OS will be changed from Unix to windows.
I am asked to test the system to check that any existing functionality that works before migration should work after migration.
I was suggested to have a look at the Installation guide to prepare the checklist. I know that the guides are available on service market place, however I am wondering which one I need to refer for the BI 7.0 installation.
Can any one please send the link of Installation guide  specifically for  BI 7.0. ?
If any one has done the similar kind of migration activity before then please share the pre and post migration test steps that you have performed during migration.
Regards,
Neeraj

Thanks Effen,
DB will remain ORACLE. I have just gone through the system copy guide . I found it bit confusing
I have prepared a list of all necessary activities and check required pre and post migration. Appreciate if you just have a look at it. Add any check that you think should be added in the list.
Pre Migration check:
SAP R3 Side:
u2022Take the snapshot of SM37 for all the LIS jobs whether it is in released state.
u2022Need to flush all the delta queues from LBWE
u2022Make the delta Queues Zero (By scheduling the respective info packages for the data targets).
SAP BW:
Analysis phase
u2022Understand the BW landscape and identify all Interfaces (SAP and Non SAP).
u2022Prepare a list of all outstanding issues of BAU. Also record all problems if any thing is broken and not working pre migration.
u2022Prepare the test scripts for technical and functional testing.
Migration Phase:
u2022Run process chain to flush all the delta queues.
u2022Remove all the jobs from Schedule position; identify all the chains based on event and Schedule chains.
u2022Stop all chains, remove them from schedule.
Post Migration check:
SAP R3 Side:
u2022Change the state of the jobs position from Schedule to Release and schedule the LBWE job to flush the records from LBWQ to RSA7 as per the one Hour frequency
u2022Check the next released job time and makes sure that the LBWE job is started sending the records from LBWQ to RSA7.
u2022Take the screen shots before sending the data from LBWQ to RSA7.
u2022Check for the number records in RSA7 as well as LBWQ.
u2022After the successful job run, check for the number of records in RSA7.
u2022Make sure that the records in RSA7 are matching with the LBWQ.
u2022Keep an eye on all the LIS jobs for two or three consequent runs.
SAP BW Side:
Technical Check:
u2022Before going to start the process chains, check all the source system connections. This includes SAP and Non SAP source systems.
u2022Check the connection of all SAP source systems with BW. Ensure that the RFC connection is established for all SAP source systems.
u2022Check the connection of all Non SAP source systems with BW. Ensure that the DB connect setting is correct and connection is established. Need to check all the source system connections through DB to make sure that all the tables/Views are not dropped out after migration. If there is any table with inactive status need to bring to the notice of the admin people of that particular database.
u2022Double check all the process chains based on Event and Schedule are successfully scheduled as per the existing timings.
u2022While scheduling the jobs, there might be some chances that system will automatically postpone the loads by one day based on the job priority defined, ensure that the jobs are running as per the scheduled date and time.
u2022Need to keep an eye on all the critical process chains like APO loads Etc... Mentioned in the excel sheet.
u2022Keep on monitoring the process chains running also compare the execution time for performance check.
u2022Randomly check the infocubes, update rules, Info objects  and other objects and verify that the objects are in active mode.
u2022Ensure that all externally scheduled processes are rescheduled Backups, DB statistics, monitoring processes, etc
u2022Verify that the connectivity with SAP portal.
u2022For verifying the BI Java configuration, run the IP transaction RSPLAN, open BI admin cockpit and check that it is working fine after migration.
u2022Verify the all infocubes administration activities like index creation/deletion, aggregate roll up, compression & DB ststistics refresh are working fine after migration.
u2022Create/delete/ maintain BW objects: DSO, infocube, infosource, update rule, transformation, DTP etc in dev systems.
u2022Check that Full Request InfoPackage, Repair Full Request InfoPackage, Initialisation with Data Request InfoPackage, Initialisation without Data Request InfoPackage and Delta Request InfoPackage can be executed successfully.
u2022Check RSRV transactions for consistency.
u2022Create, delete and modify the Query in query designer. Verify that the query designer works properly after migraition.
Functional Check:
Execute all functional test scripts and validate that the data is being loaded in all relevant info providers.
