What Can Be Reused ?

Processes that do not change betweenversions

 ± Related documentation and training materials

Technical design/code potentially not effected

by the upgrade

Upgrading to 4.x

R/3 Upgrade Assistant - Upgrade systemsremotely via a web browser 

PREPARE tool pre-loads data and helps

reduce upgrade time

Modification conflicts can be identified via

PREPARE - prior to actually upgrading

Lessons Learned

The current functionality will still exist in theupgraded system

Make sure to look at:

 ± Configuration that may have changed during the

upgrade

 ± New configuration that needs to be adjusted to

fit the current process flows

Follow a structured methodology

Similar in many ways to a straight

implementation

Lessons Learned

Even if it doesn¶t appear to be affected, test tomake sure

Schedule MANY dry run test upgrades

Upgrade project is very linear - plan

accordingly and do not expect overlap

Pay attention to the version of everythinginvolved

 ± SAP

 ± Database

 ± Operating system

 ± Interfacing systems

http://slidepdf.com/reader/full/example-of-project-life-cycle-for-r-3-migrations 21/21

Lessons Learned

Complexity of the upgrade is directly related tohow well the systems have been maintained

Select team members carefully

 ± Similar to the original implementation, they

should have a strong understanding of the

business process in their area

 ± If not, some of the processes may be overlooked
