Migrate Salesforce Classic Opportunities to Lightning instantly

SuprSwitch does not automatically convert Visualforce pages to Lightning components, as this requires code refactoring rather than data migration. However, here’s the key detail: Visualforce pages **remain fully functional in Salesforce Lightning** when accessed through classic compatibility mode or embedded in Lightning pages via special container components. SuprSwitch ensures your Visualforce page metadata, custom controllers, and associated records migrate cleanly so they’re immediately usable in Lightning without disruption. For a modernization roadmap, SuprSwitch provides a technical assessment identifying which pages would benefit most from conversion to LWC, but the migration itself keeps your business continuity intact while you plan component upgrades on your own timeline.

A typical Salesforce Classic to Lightning migration takes 2-4 weeks depending on org complexity, data volume, and customization depth. The process follows this sequence: Week 1 involves schema analysis and transformation planning; Week 2 covers a full sandbox dry-run migration with validation; Week 3 includes user testing and refinement; Week 4 executes the production cutover, which typically requires 4-8 hours of read-only mode for your organization. During cutover, your Salesforce org enters maintenance mode—users cannot create or modify records, but they retain read access to verify data completeness. SuprSwitch handles all background transformation during this window, and we perform automated validation checks to confirm record counts, field values, and relationships match source-to-target before releasing write access. Most customers are back to full productivity within the same business day.

SuprSwitch handles orgs with 500M+ total records without artificial limits, though migration performance depends on attachment volume and relationship depth. For attachments specifically, we’ve tested migrations with 10M+ files up to 10GB aggregate size; the constraint is typically Salesforce’s file storage quota rather than SuprSwitch’s engine. However, if your org has extremely deep relationship hierarchies (example: Contact → Account → Parent Account → Parent Account’s Partner Account), we recommend batching your migration in phases to reduce transformation complexity and improve validation speed. For parent-child relationships within a single object (like Account hierarchies), SuprSwitch’s transformation layer processes these sequentially to maintain referential integrity. We provide a pre-migration assessment that scans your org structure and gives you specific throughput expectations—most million-record migrations complete in under 12 hours of active processing time.

SuprSwitch provides three layers of data integrity validation: first, automated pre-cutover comparison that checks record counts, field values, and relationship integrity; second, detailed migration logs showing exactly which records succeeded, failed, or required transformation; third, a post-migration audit dashboard that compares source and target by object and field. You’ll receive a JSON validation report listing any records with mismatches, which is typically under 0.1% for standard migrations. If you discover a discrepancy after cutover, SuprSwitch maintains a 72-hour rollback window where we can revert to the pre-migration state in your Salesforce org, diagnose the issue, and re-execute the migration—this has never resulted in data loss. For slower post-cutover discovery, we can perform targeted re-migration of specific objects or records without touching the rest of your data. Our SLA guarantees 100% accuracy on standard Salesforce objects and fields, with explicit documentation of any non-standard customizations that required manual handling.
