A Technical review is a static white-box testing technique which is conducted to spot the defects early in the life cycle that cannot be detected by black box testing techniques.
Technical review is the first step for any SAP Upgrade project. Initially I struggled a bit to gather all the required information in structured format as I did not get any suitable template on internet and SDN site. Finally I have decided to prepare a generic template for any upgrade project so that I can use for any client / company. Being a SAP Basis upgrade consultant / architect, what is the most important information I need for my upgrade project, so that it will help me to smoothly execute and deliver the project on time and can cover most of the unknown(s). From my personal experience, a technical upgrade assessment is a combined effort of SAP Basis, DBA, infrastructure and functional team, primarily driven by Basis upgrade consultant or designated project manager. Since this is a technical assessment, I will not cover any functional specifications or information about affected customized programs and changes. The main focus of technical assessment is to collect information about source landscape , interfaces and target landscape – what is going to be changed and what are interdependencies. Finally, what tool you will use and how you will translate or implement these changes and resolve all interdependencies. A lot of upgrade projects need to perform both upgrade and Unicode migration; formally we called CU&UC (combine upgrade and Unicode conversion). So I will cover some of the critical assessment points of Unicode migration too.
