The Technical Upgrade Assessment Investigates:

• Technical Upgrade Timeline
  
• High level review of Customizations, including Forms, Reports, Custom VPDs and Triggers
  
• Impact of Functional Steps
  
• Problems with your Data
  
• Future Capacity Requirements
  
• Operating System Recommendations
  
• I/O Subsystem Requirements for R12.2
  
• Memory Requirements for Weblogic and the Application Tier
• Tech Stack Version Compatibility and Patch Levels, including CPUs, PSUs, RPCs and Exadata Bundles
• Current Issues from Log files
• Current unresolved service requests
• Hardware Recommendations
  
• Migration Strategies - We are DataPump experts
  
• Upgrading to Oracle Identity Management and Oracle Access Manager, to replace Single Sign-On.

If the plan includes buying new hardware, consider migrating to 64 bit Linux. Linux is the primary development platform for EBS.

• Release 11.5.10.2 doesn’t support running the Application Tier on a 64-bit hardware platform; however, Release 12 does support 64-bit architectures for the Application Tier.
• Release 12.1 and Release 12.2 all support running the database on a 64-bit operating system, in a split or mixed architecture.
• There are five hardware platforms supported for Release 12.1 and all of the platforms support a 64 bit version.
• There are less memory restrictions on a 64-bit machine because of additional addressable memory.
• Because of more addressable memory, more users can be supported on each Application Tier.
• MRP and other programs run much more quickly in a 64-bit database.
