The Stakes Are Higher Than You Think
A CMMS data migration isn't just an IT project – it's a transformation that will define your maintenance operations for the next decade. Get it right, and you unlock efficiency gains worth millions. Get it wrong, and you'll be apologizing to technicians for years.
This guide distills lessons from 100+ migrations across manufacturing, utilities, and facilities management. Whether you're moving from Excel, Access, or another CMMS, this is your roadmap to success.
Pre-Migration: The Foundation (Weeks 1-2)
Step 1: Data Discovery and Assessment
Before touching any data, document what you have:
Inventory your data sources:
- Primary CMMS database
- Spreadsheet supplements (yes, we know they exist)
- Paper records and tribal knowledge
- Integration points with ERP/financial systems
Assess data quality metrics:
Completeness Score: [Filled fields / Total fields] × 100
Accuracy Score: [Verified correct / Sample size] × 100
Consistency Score: [Standardized records / Total records] × 100
Uniqueness Score: [Unique records / Total records] × 100
Red flags to address immediately:
- Completeness below 60%
- Duplicate assets above 10%
- Missing hierarchy relationships above 30%
- Inconsistent naming conventions
Step 2: Define Your Target State
Choose your standards:
- ISO 14224 for oil & gas and process industries
- RDS-PP for petroleum and petrochemical
- RDS-PS for power generation
- KKS for power plants
- SFI for marine and shipping
Map critical data fields:
| Legacy Field | Target Field | Transformation Rule | Priority | |-------------|--------------|-------------------|----------| | EQUIP_ID | Asset_Number | Standardize format XXX-YYYY-ZZ | Critical | | DESC | Asset_Description | Limit 100 chars, remove special chars | High | | LOCATION | Functional_Location | Map to hierarchy | Critical | | MAINT_TYPE | PM_Category | Standardize values | Medium |
Step 3: Build Your Migration Team
Essential roles:
- Migration Lead (decision maker)
- Data Analyst (quality control)
- System Expert (legacy system)
- CMMS Admin (target system)
- Operations Representative (validation)
Data Staging: Where Success Happens (Weeks 3-5)
The Extract-Transform-Load (ETL) Process
Extract: Getting Data Out Safely
From legacy CMMS:
-- Example extraction query
SELECT
asset_id,
asset_description,
location_code,
manufacturer,
model_number,
serial_number,
install_date,
criticality
FROM assets
WHERE status = 'ACTIVE'
ORDER BY location_code, asset_id;
From spreadsheets:
- Consolidate all spreadsheets into a master workbook
- Standardize column headers
- Remove formatting and formulas
- Export as CSV for processing
Transform: The Heavy Lifting
Asset naming standardization:
Before: "Pump 1", "PUMP-001", "Centrifugal Pump #1"
After: "PMP-AREA-001" (following agreed convention)
Hierarchy construction:
Level 1: Site (SITE-01)
Level 2: Area (AREA-101)
Level 3: System (SYS-101-COOL)
Level 4: Equipment (PMP-101-COOL-001)
Level 5: Component (BRG-PMP-101-COOL-001)
PM standardization example:
Original PMs for identical pumps:
- "Check oil level monthly"
- "Oil inspection - 30 days"
- "Monthly oil check"
Standardized PM:
- Task: "Lubrication Inspection"
- Frequency: 30 days
- Duration: 0.5 hours
- Craft: Mechanical
- Instructions: [Standardized checklist]
Load: Strategic Import
Phased loading approach:
Phase 1: Static Data
- Sites and areas
- Asset types and categories
- Failure codes
- Work order types
Phase 2: Asset Master Data
- Equipment hierarchy
- Asset attributes
- Spare parts linkages
- Documentation
Phase 3: Maintenance Plans
- PM schedules
- Job plans
- Safety procedures
- Routes
Phase 4: Historical Data
- Last 2 years of work orders
- Failure history
- Cost data
- Performance metrics
Data Validation Checkpoints
Run these validations after each phase:
✓ Hierarchy Integrity Check
- Every asset has a parent (except top level)
- No circular references
- No orphaned records
✓ Referential Integrity Check
- All foreign keys valid
- No broken relationships
- Spare parts linked correctly
✓ Business Rules Check
- PM frequencies logical (not 0 or 999999)
- Costs within reasonable ranges
- Dates in correct format and range
✓ Completeness Check
- Mandatory fields populated
- Critical assets have full data
- PM instructions present
Migration Execution: Game Day (Week 6)
Pre-Migration Checklist
□ Full backup of legacy system completed
□ Target system configured and tested
□ All users notified of blackout period
□ Data staging environment validated
□ Rollback plan documented
□ Success criteria defined
Migration Sequence
Day 1: Foundation
- Load organizational structure
- Import user accounts and permissions
- Configure system settings
Day 2-3: Core Data
- Import asset hierarchy
- Load equipment attributes
- Create PM schedules
Day 4: Validation
- Run automated checks
- User acceptance testing
- Fix critical issues
Day 5: Go-Live
- Final data sync
- System cutover
- Monitor and support
Post-Migration: Ensuring Adoption (Weeks 7-8)
Immediate Actions
-
Data Governance Implementation
- Lock down critical fields
- Implement approval workflows
- Set up data quality monitoring
-
User Training Focus Areas
- Finding assets in new structure
- Creating work orders correctly
- Following PM schedules
-

- Run basic equipment reports
- Complete first work orders
Common Pitfalls and Solutions
| Pitfall | Impact | Solution | |---------|--------|----------| | Incomplete spare parts mapping | Stockouts, delays | Map parts before go-live | | Missing PM instructions | Inconsistent maintenance | Standardize procedures first | | Poor hierarchy design | Can't track costs | Redesign before migration | | Inadequate training | User resistance | Hands-on sessions, job aids | | No data governance | Quality degradation | Implement controls day 1 |
