• Rehost– Move Compute instances, tooling on virtualization

layer moves O/S and up to OCI– 80% of core applications migrated using tooling

• Replatform– Create new compute on target, use application tools

to migrate workload– JDE – Upgrade to 9.2. JDE team retrofits

customizations on 9.2 and deploys on new applications

– Database migration - GoldenGate

• Refactor– OCI Load Balancers– Retire/replace Oracle Traffic Director

• Databases on containers with tablespace encryption• Taking advantage of availability domains within region for smarter DR

– Skipping number of standbys– Reduced number of instances by 100

• High availability through LBaaS and regional subnets• Efficient use of OCI services, higher performance compute

– Reduced number of cores to half

• Simplified management – reduced footprint– Infrastructure as Code using Terraform

CHALLENGES

BSSV bad codingproblem appeared after Go-Live

WebCenter Upgradeto move to OCI

Firewall openingsthe most time disturbing and time consuming activity

SOA interfaces «when done is done»e2e verification time consuming

Common test strategy missing for OCI and JDEUPnot possible to test in QA need to postpone till Pre-Prod

COMMERCIAL BENEFITS

Leverage on-demand modelwill reduce OPEX costs in future

Mid-term Oracle migration program

OCI contract is Global

LESSONS LEARNED

Build better Communication PlanBusiness Leaders to communicate to Business usersNot enough IT to communicate to Super Users, IT Mgmt, Business Mgmt

Be prepared for a long downtime

Interfaces in E2E Business Process context

KNOWLEDGE BUILT ABOUT…

ü Our APPLICATION SUITES and how they WORK TOGETHER

ü INFRASTRUCTURE and how to EFFECTIVELY MANAGE it

ü TROUBLESHOOTING and how to FIND ISSUES FAST

ü TROUBLESHOOTING and how NOT DO IT

ü The VALUE OF ACCURACY and need for eyes on DETAILS

Never ever ever ever give up!

Still TO DO…

Optimize the use of the platform

Load Balancing for JDE enterprise servers

Single Sign On performance
