Great Plains, Sage Intacct
1Challenge
Legacy Great Plains system was end-of-life with no vendor support. Years of dimension sprawl made the chart of accounts unmanageable, and historical data needed to be preserved for compliance.
2Requirements
- Full historical data migration (7 years)
- Chart of accounts rationalization
- Dimension cleanup and standardization
- Parallel run validation
- Zero downtime cutover
3Solution
We developed a comprehensive migration plan with COA mapping, dimension consolidation, and historical data transformation. A parallel run period validated accuracy before the final cutover.
Key Features
COA Rationalization: Cleaned up 40% of unused accounts
Dimension Cleanup: Standardized naming and hierarchy
Historical Load: 7 years with full audit trail
Validation Framework: Automated balance reconciliation
