Have a Champion within the development team

“1:1”-Migration of the existing approach helped teams to move to new platform

Infrastructure knowledge needed (System i and IBM WebSphere Application Server)

Because of good planning transition was rather smooth

Don´t forget the people!

LESSONS LEARNED DURING

TRANSITION

www.cwi.at 31

„The genius of a construction lies in its simplicity. Everybody can build complicated things” (Sergei P. Korolev)

“A Rule is a good Rule when it makes you faster”

Reassess old paradigms and architecture

Devide and rule

Phase model makes it easier to break the transition into small and better controllable pieces

CONCLUSION

“We at UniCredit Leasing Austria have opted for the combined toolset of Rational Team Concert for IBM i and Rational Developer

for IBM i because they provide us with the best support for modern approaches to software engineering for the

IBM i platform.” - Mircea-Dan Antonescu
