Answer 1

Dear,
Check Before upgradation
For upgrade a BW consultant first needs to find out what are the new features , bugs that are coming in with the upgrade. You can find this in the release notes and related OSS notes.
Next the BW consultant needs to identify and create test scripts to test data loads, custom functionality, reports, security and any other custom process that is currently in place.
Before the upgrade the BW consultant needs to execute all the test scripts and record the before images.
Post upgrade the consultant needs to re execute the same scripts and make sure things are working as they are suppossed to.
If not then the BW consultant needs to work with BASIS, Security or SAP teams to resolve those issues.
Wats will happen after migration
SAP with little of enhancements go with 3.x ,if NOT go with 7.0
rationale - with 7.0 dataflow all the update rules,transfer rules will get deleted automatically and so you have to do all those ABAP coding delivered by SAP on your own now manually in the new world called Transformations .
DS should be Migrated and total infrastructure will changes.
yes you can copy the existing IP from 3.5 to 7.0, but only change is you have to create Transformations.
If it is R/3 then no need to create DS seperately, you can Migrate them.
Emulating Data source
You can try the
Emulated DataSource_--> means ---upgraded 3.x datasource(you will see square symbol on the emulated datasource) which could also use BI 7.0 capabilities along with 3.x loading methodlogy.(both paths are available).
But once you migrate an emulated DataSource it completely becomes BI 7.0 datasource(using transformation and DTP) and you no longer can use the 3.x way of loading (using transfer rule ,update rule etc).
Check properly the new way of loading before migration of datasources to bi 7.
