Quick Answer

What is the best CRM migration service?

The best CRM migration service guarantees zero data loss with a 99.7%+ integrity rate through structured audit, cleansing, staged execution, and rigorous validation. AavishkarIT has delivered 500+ migrations from Salesforce, HubSpot, Dynamics, Zoho, Pipedrive, spreadsheets, and legacy systems using a 6-phase framework: discovery, field mapping, data cleansing, migration execution, validation, and cutover. We preserve workflows, relationships, and attachments while minimizing downtime.

Why CRM Migrations Fail Without Expertise

These are the root causes that turn migration projects into expensive disasters.

Fear of Data Loss

Critical Risk

Leadership hesitates because they cannot verify what will survive the transition. Missing records, broken relationships, and orphaned attachments create business risk that stalls migration decisions for months.

Field Mapping Complexity

Every source system uses different field names, data types, and relationship models. Mapping thousands of fields manually leads to errors, mismatched data, and reporting that no longer makes sense post-migration.

Business Downtime Risk

Critical Risk

Cutting over to a new CRM without a staged migration plan means hours or days of downtime. Sales teams cannot access leads. Support cannot resolve tickets. Revenue stops flowing while systems are in limbo.

Duplicate Record Proliferation

Legacy CRMs accumulate duplicates over years of use. Migrating without deduplication means the new system starts with the same data quality problems. Reps waste time on redundant records. Reports become unreliable.

Validation Gaps

Most migrations skip rigorous validation. Teams assume the data looks right because the row counts match. But hidden issues surface weeks later: missing custom fields, broken lookups, truncated text, corrupted attachments.

User Adoption Collapse

Critical Risk

When migrated data is incomplete or inaccurate, users lose trust immediately. They revert to spreadsheets, shadow systems, or the old CRM. The migration investment is wasted because the team refuses to use the result.

Our 6-Phase Migration Framework

Every migration follows the same proven process. No guesswork. No shortcuts. No data loss.

Discovery & Audit

1-2 weeks

Comprehensive audit of source system objects, fields, relationships, attachments, workflows, and customizations. We document data volume, quality scores, and complexity factors to build a migration blueprint.

Field Mapping & Transformation

1-2 weeks

Create detailed field-level mappings between source and target systems. Handle data type conversions, relationship reconstruction, picklist standardization, and custom object translation.

Data Cleansing & Deduplication

1-3 weeks

Cleanse records before migration — standardize formats, fill gaps with enrichment, merge duplicates using fuzzy matching, and flag anomalies for manual review. Starting clean is faster than fixing later.

Migration Execution

1-4 weeks

Execute staged migration with dry runs, incremental loads, and parallel validation. Use automated scripts for bulk transfers and manual handling for edge cases. Monitor every batch for errors and anomalies.

Validation & Reconciliation

1-2 weeks

Rigorous validation including row counts, field-level sampling, relationship integrity checks, attachment verification, and business rule testing. Reconcile discrepancies and certify data accuracy before go-live.

Cutover & Optimization

1 week

Execute the final cutover during a planned maintenance window. Run delta sync for records changed during migration. Optimize indexes, verify integrations, and hand over a clean, production-ready system.

Migration Scenarios We Handle

From simple upgrades to complex multi-system consolidations.

Same-Platform Upgrade

Upgrading within the same CRM family — e.g., Salesforce Classic to Lightning, or Creatio 7.x to 8.x. Preserve customizations while modernizing the platform foundation.

Cross-Platform Migration

Moving from one CRM to another — e.g., Salesforce to Creatio, HubSpot to TWOZO, or Dynamics to Zoho. Full data model translation with field mapping and workflow recreation.

CRM Consolidation

Merging multiple CRM instances or systems into a single unified platform. Common after acquisitions, regional rollups, or departmental consolidation initiatives.

Spreadsheet-to-CRM Migration

Transforming Excel or Google Sheets-based sales and customer tracking into a structured CRM. Includes data modeling, validation rule design, and process digitization.

Frequently Asked Questions

How long does a typical CRM migration take?

Timeline depends on data volume and complexity. A simple spreadsheet-to-CRM migration: 2-4 weeks. A mid-complexity cross-platform migration (e.g., HubSpot to Creatio): 6-10 weeks. A large enterprise consolidation with 500K+ records: 12-16 weeks. Our audit phase gives you a precise estimate before work begins.

Will we lose data during migration?

No. We have delivered 500+ migrations with zero data loss. Our process includes full backup before cutover, staged validation after every batch, and reconciliation reports that verify every record, field, and attachment. We never cut over until accuracy is certified above 99%.

Can you migrate from our custom-built CRM?

Yes. We have migrated from proprietary systems, Access databases, custom PHP/MySQL CRMs, and legacy ERP modules. The approach is the same: audit the data model, build extraction scripts, map to the target schema, and validate thoroughly. Custom systems often require more discovery but are fully migratable.

What happens to our workflows and automations?

Workflows and automations do not migrate automatically — they are platform-specific. We document your existing workflows during discovery, then rebuild them in the target platform using native tools (Creatio process designer, TWOZO workflows, Salesforce Flow, etc.). This is often an opportunity to simplify and improve them.

Do we need to stop using the current CRM during migration?

No. We build and test the migration in parallel using sandbox or staging environments. Your team continues using the live system. The final cutover happens during a planned window — typically 2-8 hours — with a delta sync for records changed during the window.

How much does CRM migration cost?

Migration costs range from $3,000 for simple spreadsheet migrations to $75,000+ for enterprise consolidations with complex data models. Factors include source platform, record volume, attachment size, custom object count, deduplication complexity, and validation rigor. Use our Data Migration Cost Estimator for a tailored quote.

What if we have dirty data with lots of duplicates?

That is exactly why the cleansing phase exists. We use fuzzy matching algorithms to identify duplicates, standardize formats, fill gaps with enrichment services, and flag edge cases for your team to review. Starting with clean data in the new CRM is one of the biggest ROI drivers of migration.

Do you provide post-migration support?

Yes. Our Managed Excellence program provides ongoing admin support, reporting refinement, workflow optimization, and data quality monitoring after migration. Many clients start with a migration engagement and transition to managed support to keep their new CRM improving over time.
