Platform migration paths we specialize in

Salesforce to HubSpot CRM migration services

Salesforce → HubSpotCRM migration

Salesforce to HubSpot migration: contacts, deals, workflows & custom objects

The most requested CRM migration path. We transfer contacts, companies, deals, tickets, custom objects, and engagement history from Salesforce to HubSpot—including picklist values, record owners, and multi-currency fields that other migration tools miss. Our Salesforce to HubSpot migration includes rebuilding Apex triggers as HubSpot workflows, converting Salesforce reports into HubSpot dashboards, and remapping permission sets to HubSpot teams. We also handle Salesforce CPQ data, custom Lightning components, and Pardot-to-HubSpot marketing migration when both platforms are being consolidated.

On-premise to AWS cloud migration services

On-Premise → AWScloud migration

On-premise to AWS migration: servers, databases, applications & workloads

We migrate on-premise infrastructure to Amazon Web Services using AWS Migration Hub, Application Migration Service, and Database Migration Service. Our on-premise to AWS migration covers virtual machine rehosting (VMware, Hyper-V), database engine conversions (Oracle to Aurora PostgreSQL, SQL Server to RDS), and application refactoring for cloud-native architecture. We handle VPC network design, IAM security policies, S3 storage migration, and hybrid connectivity via Direct Connect or VPN—ensuring your AWS environment is production-ready with auto-scaling, load balancing, and disaster recovery configured from day one.

Legacy ERP to Microsoft Dynamics 365 migration

Legacy ERP → Dynamics 365system modernization

Legacy ERP to Dynamics 365 migration: Oracle, SAP, custom systems & mainframes

We specialize in migrating legacy ERP systems—Oracle E-Business Suite, SAP ECC, custom-built databases, and even mainframe applications—to Microsoft Dynamics 365 Finance & Operations or Business Central. Our legacy to Dynamics 365 migration includes direct database extraction from Oracle, SQL Server, Informix, or flat-file systems, schema transformation to Dynamics 365 data entities, and historical transaction preservation with full audit trails.

Oracle database to PostgreSQL migration services

Oracle → PostgreSQLdatabase migration

Oracle to PostgreSQL migration: schemas, stored procedures, PL/SQL & performance tuning

We migrate Oracle databases to PostgreSQL—the most popular open-source alternative—reducing licensing costs by up to 90%. Our Oracle to PostgreSQL migration converts PL/SQL procedures to PL/pgSQL, transforms Oracle-specific data types (VARCHAR2, NUMBER, CLOB) to PostgreSQL equivalents, and rewrites Oracle packages as PostgreSQL functions and extensions. We handle sequence migration, materialized view recreation, partitioned table conversion, and Oracle-specific SQL syntax translation. Performance tuning is included: we analyze query execution plans, configure PostgreSQL shared_buffers and work_mem for your workload, and implement pg_stat_statements monitoring to match or exceed your Oracle performance baseline.

Why Data Migration Projects Fail (And How We Prevent It)

Data Loss & Corruption

The nightmare scenario: you complete migration only to discover critical records are missing, corrupted, or duplicated. Historical data that took years to accumulate—gone. Customer relationships, transaction history, compliance records—all at risk.

Why it happens: Inadequate data mapping between source and destination schemas. No validation checks during transfer. Rushing to meet deadlines without proper testing. Overlooking edge cases and special characters.

How we prevent it: Comprehensive data audit before migration begins. Field-by-field mapping documentation reviewed by both technical and business teams. Automated validation scripts that compare source and destination at every level. Pilot migrations with representative data subsets.

Our guarantee: Zero data loss, guaranteed. We run parallel systems during transition and validate every record. If any data is missing post-migration, we recover it at no additional cost.

Frequently Asked Questions

How long does a typical migration take?

Migration timelines vary based on data volume and complexity. Here are typical ranges:

Simple migrations (single system, clean data): 4-6 weeks.

Moderate migrations (multiple systems, custom configurations): 2-3 months.

Complex migrations (legacy systems, large datasets, many integrations): 3-6 months.

Enterprise migrations (multiple business units, compliance requirements): 6-12 months.

We provide detailed timelines during the discovery phase based on your specific situation.

Will there be any downtime during migration?

We minimize downtime through careful planning and proven strategies:

Phased migration: Transfer data in stages during off-peak hours, with final cutover during a planned maintenance window.

Parallel running: Keep both systems operational during transition, allowing gradual user migration and rollback capability.

Real-time sync: For critical systems, we implement bidirectional synchronization so both systems stay current until cutover.

Most migrations are completed with less than 4 hours of downtime. Critical systems can often be migrated with zero downtime using these strategies.

How do you ensure zero data loss?

Data integrity is our #1 priority. Our multi-layer validation process includes:

Pre-migration audit: Complete inventory of all records, fields, and relationships.

Pilot testing: Test migrations with representative data subsets to validate mapping rules.

Automated validation: Scripts compare source and destination record counts, field values, and relationships.

Manual spot-checks: Human verification of critical records and complex data structures.

Rollback capability: Full backups and restore procedures tested before production migration.

Post-migration reconciliation: Comprehensive reports comparing source and destination data.

We guarantee zero data loss—if any data is missing, we'll recover it at no additional cost.

What happens if something goes wrong?

We plan for every contingency:

Complete backups: Full source system backups before any migration activity.

Rollback procedures: Tested restore processes that can revert to previous state within hours.

24/7 monitoring: Real-time alerts during migration with immediate escalation for any anomalies.

Contingency resources: Additional engineers on standby during critical migration windows.

Communication protocols: Clear escalation paths and regular status updates throughout.

In 500+ migrations, we've never lost data or caused extended unplanned downtime.

Can you migrate custom configurations and workflows?

Yes—custom configurations are often the most valuable part of your system. We migrate custom fields and objects with complete schema recreation, workflow rules, automations, and business logic, validation rules and formula fields, custom reports and dashboards, API integrations and connected apps, user permissions, roles, and profiles, and email templates and document generation. During discovery, we document every customization to ensure nothing is lost in translation.

What factors affect migration complexity?

Several key factors determine the scope and complexity of a migration project:

Data volume: Number of records, file attachments, and historical data to be moved.

System complexity: Custom fields, workflows, automations, and business logic that need to be recreated.

Integration landscape: Connected systems that need to be re-mapped to the new platform.

Data quality: Duplicate records, inconsistent formats, and data cleanup requirements.

Compliance requirements: Regulatory standards (GDPR, HIPAA, SOC 2) that impact handling and documentation.

Downtime tolerance: Whether you need zero-downtime migration or can accept a maintenance window.

We provide free discovery sessions to assess your specific situation and recommend the right approach.

Do you provide training after migration?

Yes, comprehensive training is included in all migration projects:

System orientation: Overview of the new platform and key differences from the old system.

Role-based training: Customized sessions for administrators, power users, and end users.

Documentation: Written guides, video tutorials, and quick-reference materials.

Knowledge transfer: Technical documentation for your IT team on configurations and integrations.

90-day support: Ongoing Q&A and troubleshooting during the transition period.

We don't consider a migration complete until your team is confident and productive on the new system.

Can you migrate from legacy systems without APIs?

Yes—we have extensive experience with legacy system migrations where no modern API exists:

Database extraction: Direct access to Oracle, SQL Server, MySQL, Access, or custom databases.

File parsing: Extract data from flat files, CSV exports, XML, or proprietary formats.

Screen scraping: Automated data extraction from legacy application interfaces when necessary.

ETL pipelines: Custom extraction, transformation, and loading processes for complex data.

Manual digitization: OCR and data entry services for paper-based records when needed.

We've successfully migrated data from 25+ year-old systems that vendors no longer support.

What about data cleanup during migration?

Data cleanup is a standard part of our migration process—your new system will have cleaner data than your old one:

Duplicate detection: Identify and merge duplicate records based on configurable matching rules.

Format standardization: Normalize phone numbers, addresses, names, and other fields.

Data enrichment: Fill missing fields using third-party data sources when appropriate.

Invalid data flagging: Identify records with missing required fields or invalid values.

Relationship cleanup: Fix orphaned records and broken relationship references.

Many clients view migration as an opportunity for a 'fresh start' with high-quality data.

Can we do a phased migration?

Yes, phased migrations are often recommended for large or complex projects:

By module: Migrate CRM first, then marketing, then support—allowing teams to adapt gradually.

By business unit: Migrate department by department or region by region.

By data type: Move active records first, historical data second.

By risk level: Start with lower-risk data to validate processes before migrating critical systems.

Parallel operation: Run both systems simultaneously during transition with bidirectional sync.

Phased approaches reduce risk, allow for learning and adjustment, and minimize business disruption.
