Installation Steps for SuiteCRM
To install SuiteCRM:

- Create a MySQL database
- Run the web installer and follow prompts

Post-installation, enable two-factor authentication and schedule regular backups.
Data Migration and Import Best Practices
Migrating existing customer data is crucial. Use CSV imports for contacts, leads, and deals. Always:
- Clean data before import (remove duplicates, fix formatting)
- Map fields correctly during import
- Test with a small dataset first
Most CRMs provide sample templates to ensure compatibility.
