Upgrade of GRC AC 5.3 to 10.1

The main steps to upgrade from 5.3 to 10 for Access Control are listed below: 
SAP provides a migration tool with capability to export data from existing Access Control 4/5.3 to Access Control 10.0
• Java-based versions 5.2/5.3 cannot be upgraded directly to ABAP-based version 10.0 due to the difference in platform
• The migration tool provides following functionalities:
- Automated process with limited manual effort
- Ability to transfer configuration data, which includes SAP connectors, RAR configuration parameters, ERM configuration parameters, as well as CUP configuration parameters
- Export master data, including user roles and rule sets
- Ability to export data onto a spreadsheet and customize it before import
- Flexibility to filter and modify data before export
• Ensure SAP NetWeaver is at least 7.0 SP11 and AC 5.3 SP13
• Access Control 5.2 will first need to be upgraded to version 5.3
• Complete the configuration in IMG for the SAP connectors and new components
- Refer to the GRC 10.0 Configuration Guide for more information
• Create appropriate owners/users within Access Control 10.0
• Create the appropriate Org. Unit to import the RAR data
• Before migrating CUP and ERM data, manually create all AC 5.3 custom fields in GRC 10.0 using identical names
• Activate Business Configuration Sets (BCSETS) for 10.0 based on details in the migration guide
• Upgrade the RTA in the ERP back end to the new GRC 10.0 plug-ins
For Process Control, it is a direct upgrade to the NW 7.02/7.31 and then the GRC 3.0 --> 10 upgrade.  There is a guide from SAP with all the details for PC 3.0 --> 10 upgrade.
