Understanding SIS vs LMS: What's the Difference?
Before diving into migration strategies, it's crucial to understand the distinct roles of Student Information Systems (SIS) and Learning Management Systems (LMS), as they store different types of data and serve different purposes within your school's technology ecosystem.
| Feature | SIS (Student Information System) | LMS (Learning Management System) |
|---|---|---|
| Primary Purpose | Administrative records management | Course delivery and instruction |
| Core Data | Enrolment, demographics, scheduling, grades, attendance, transcripts | Course content, assignments, discussions, quizzes, rubrics, submissions |
| Primary Users | Registrars, administrators, counselors, business office | Teachers, students, instructional designers |
| Typical Systems | PowerSchool, Infinite Campus, Skyward, Aeries, Synergy | Canvas, Blackboard, Schoology, Moodle, Google Classroom |
Many schools are now migrating from legacy SIS platforms to modern LMS platforms, or integrating both systems. Some migrations involve moving data directly between these systems, while others involve consolidating both into a unified platform like a school ERP.
Phase 1: Planning Your SIS to LMS Migration
Proper planning is the difference between a smooth migration and a semester-long disaster. Here's what you need to determine before writing any code or exporting any files:
Define Migration Scope
- What data are you migrating? Just current term grades? Historical grades? Course rosters? Assignment scores? Attendance? Determine exactly which data types need to move.
- What's the time horizon? Are you migrating only current students, or do you need alumni records? How many years of historical data are required?
- Is this a one-time migration or ongoing sync? Some schools migrate once and then retire the old system. Others set up ongoing synchronization between SIS and LMS.
Audit Source and Target Systems
- Export schema documentation from both systems. What fields exist? What are their data types? Which fields are required vs optional?
- Identify custom fields in your SIS that may not have direct equivalents in the LMS.
- Check API availability β many modern SIS and LMS platforms offer REST APIs that are far more reliable than CSV file imports.
- Review vendor documentation for migration tools. Canvas, for example, has SIS Import tools designed specifically for PowerSchool and other major SIS platforms.
Create a Migration Timeline
- Best window: Summer break (June-August) when academic activity is minimal
- Second best: Winter break (2-3 weeks in December-January)
- Avoid: Beginning or end of term, exam periods, or registration windows
Phase 2: Data Preparation
Data preparation is often the most time-consuming phase but also the most important for ensuring data quality in your new LMS.
Step 1: Extract Data from SIS
Most SIS platforms offer export functionality. Common export formats include:
- CSV/TSV files β Universal but prone to encoding issues
- Excel (XLSX) β Easy to work with but limited to ~1 million rows
- JSON via API β Best for large datasets and ongoing syncs
- XML β Common in older enterprise systems
Export the following key data sets separately:
- Students β Unique student IDs, names, grade levels, contact information
- Courses β Course codes, names, departments, credit values
- Sections/Classes β Course sections with period, room, teacher assignments
- Enrolments β Which students are enrolled in which sections
- Grades β Final grades, term grades, assignment scores (if applicable)
- Teachers β Staff IDs, names, email addresses, department assignments
Step 2: Clean Your Data
SIS data often contains years of accumulated errors and inconsistencies. Address these before migration:
- Remove duplicate student records β Duplicate IDs for the same student are common in older systems
- Standardize date formats β Ensure all dates use the same format (YYYY-MM-DD is recommended)
- Validate email addresses β Email format errors will prevent login access to the LMS
- Check for orphaned records β Grades without student IDs, enrolments without sections, etc.
- Handle special characters β Accented names (JosΓ©, SΓΈrensen) and apostrophes (O'Connor) often break CSV imports
Step 3: Map Fields to Target LMS
This is the most critical technical step. Create a mapping document showing how each SIS field corresponds to LMS fields:
| SIS Field Name | LMS Field Name | Transformation Required |
|---|---|---|
| student_id (int) | user_id (string) | Convert to string, zero-pad to 8 digits |
| full_name | display_name | Split into first/last, then combine |
| dob (MM/DD/YYYY) | birth_date (YYYY-MM-DD) | Date format conversion |
| grade_level (9,10,11,12) | graduation_year | Calculate from current year |
| final_grade (A-) | computed_current_score | Convert letter grade to percentage |
Phase 3: Executing the Data Transfer
With planning and preparation complete, it's time to execute the actual migration.
Test Migration (Critical Step!)
- Run on a staging environment β Never test on production systems
- Use a representative sample β Include students from different grade levels, courses from different departments, and edge cases (transfer students, students with IEPs, etc.)
- Validate results thoroughly β Check record counts, field values, and relationships
- Fix issues and repeat β Run at least 2-3 test cycles until no errors remain
Full Migration Execution
When you're ready for the full migration:
- Schedule during low-activity period β Communicate the downtime window to all stakeholders
- Take a full backup of both source and target systems before starting
- Lock write access to the source SIS during the final sync to prevent changes that would create discrepancies
- Execute in this order: Students β Courses β Sections β Enrolments β Grades
- Monitor logs in real-time β Have someone watching for errors during the entire transfer
- Document everything β Keep a detailed log of timestamps, record counts, and any anomalies
Migration Methods Comparison
| Method | Best For | Pros | Cons |
|---|---|---|---|
| CSV Import | Small schools (<500 students) | Simple, no coding required | Manual, error-prone, no validation |
| API Integration | Medium/large schools | Automated, repeatable, can sync ongoing | Requires developer resources |
| ETL Tool | Complex migrations | Handles transformations, logging, scheduling | Costly ($5k-20k) |
| Vendor Migration Service | Schools with budget | Handled by experts, warranty | Expensive ($10k-50k+) |
Phase 4: Post-Migration Validation
The migration isn't complete until you've proven that data arrived correctly and is usable.
Automated Validation
- Compare record counts β Every table in source should match target within 0% variance
- Run checksum validation β For critical fields like student IDs and final grades
- Check foreign key integrity β Every enrolment should reference an existing student and existing section
Manual Spot-Checking
- Select 10-20 random students from different grades and demographics
- Verify end-to-end β Look up each student in both systems and compare every key field
- Test login access β Create test accounts and verify that students and teachers can log into the LMS
- Run critical reports β Generate transcripts, grade reports, and class rosters in both systems and compare
User Acceptance Testing
- Recruit pilot users β 3-5 teachers and 10-15 students from each grade level
- Ask them to perform normal tasks β Check grades, submit assignments, post to discussion boards
- Collect structured feedback β Use a simple survey to capture issues
- Fix issues before full rollout β Don't launch to everyone until your pilot group confirms everything works
Common SIS-to-LMS Migration Pitfalls (And How to Avoid Them)
Pitfall #1: Assuming Direct Field Matches
The problem: You assume that "final_grade" in your SIS maps directly to "current_score" in your LMS, but the LMS expects a percentage (0-100) while your SIS uses letter grades (A-F).
The fix: Create a transformation mapping table. For example: A = 95, A- = 91.5, B+ = 88.5, etc. Test this conversion thoroughly.
Pitfall #2: Forgetting About File Attachments
The problem: You migrate student records but forget about IEP documents, health records, and assignment submissions attached to the old system.
The fix: Inventory all file attachments before migration. For LMS migrations, assignment submissions are often the largest dataset and require special handling (usually via API).
Pitfall #3: UTF-8 Encoding Errors
The problem: Student names with accents (JosΓ©, ClΓ©mence) or special characters appear as gibberish (JosοΏ½) after import.
The fix: Save all CSV files as UTF-8, not ANSI or ASCII. Use a text editor that shows encoding (like VS Code or Notepad++) to verify.
Pitfall #4: Not Testing with Realistic Data Volume
The problem: Your test migration works perfectly with 50 students, but the full migration with 5,000 students times out or fails due to API rate limits.
The fix: Test with at least 10% of your production data volume. If your LMS API has rate limits (e.g., 100 requests per minute), build in delays.
Pitfall #5: Migrating During Active Use
The problem: You migrate during the school day while teachers are updating grades, creating data mismatches between source and target.
The fix: Always schedule migrations during off-hours. For ongoing changes, implement a delta sync or lock the source system during the final migration window.
Frequently Asked Questions
Q: Can we keep using our SIS after migrating to an LMS?
A: Yes, many schools maintain both systems, using the SIS for administrative records and the LMS for course delivery. In this model, you typically need ongoing synchronization (e.g., nightly updates) to keep rosters and grades in sync.
Q: How long does an SIS to LMS migration take?
A: Timeline depends on school size and data complexity. Small schools (under 500 students) can complete in 2-3 weeks. Medium schools (500-2,000 students) typically need 4-6 weeks. Large districts (multiple campuses) should plan for 8-12 weeks.
Q: Do we need to hire a consultant for SIS to LMS migration?
A: Not necessarily. Many SIS and LMS vendors offer free migration tools or import wizards. Canvas, for example, has a "SIS Import" tool designed for PowerSchool data. However, if your data is highly customized or you have unusual requirements, a consultant may save time and prevent errors.
Q: What happens to old assignment submissions when migrating between LMS platforms?
A: This is the most challenging part of LMS-to-LMS migration. Many assignment submissions (essays, projects, multimedia) need to be migrated via API or manually. Some schools choose to archive old courses read-only in the old LMS rather than migrating every submission.
Q: How do we handle courses that are still in progress during migration?
A: The best practice is to migrate after grades are finalized for the term. If you must migrate during an active term, you'll need to map partial grades and ongoing assignments carefully. Consider a "phased migration" where you migrate past terms first, then current term data after it's complete.
