Informations about migration XI3.1 TO BI4.2 SP9

Hi everyone

I work on a project of migration to sap XI3.1 to SAP BI 4.2 SP9.

Could you tall me please

• Pitfalls to avoid • Advice / recommendations to follow

• the points of attention to be monitored Also, do you have any documentation to share with me? I am thinking in particular of • framing notes, • technical migration documents, • server sizing docs / info (CMC / CMS / web) • any other document deemed useful

and also do you know if a tool exist to compare the different object before migration and after migration.

How to choose the report to migrate

Thank you by advance.
