Full migration from GA4, legacy CRMs, custom data stacks, and third-party platforms into Customer360's first-party vault — including data cleaning, deduplication, enrichment, and compliance mapping. Your history comes with you.
Your data is currently scattered across platforms that own it, sample it, or can delete access at any time. One migration changes all of that — permanently.
Export and reconstruct your full analytics history — events, conversions, audience segments, and custom dimensions — into C360's privacy-safe, unsampled vault.
Full contact database migration from Salesforce, HubSpot, Zoho, Microsoft Dynamics, and custom CRMs — with relationship maps, activity history, and deal stages preserved.
Migrate subscriber lists, engagement history, segments, and campaign data from Mailchimp, Klaviyo, Sendinblue, ActiveCampaign, and legacy ESP stacks.
Secure migration from core banking systems, insurance platforms, and on-premise data warehouses — with full audit trails and RBI/IRDAI compliance documentation.
Customer purchase history, behavioural data, and loyalty programme data from Shopify, WooCommerce, Magento, and custom eCommerce backends — mapped to 360° customer profiles.
ETL from custom databases, data lakes, warehouses (BigQuery, Redshift, Snowflake), and bespoke applications — including schema mapping and transformation logic.
Every platform you've ever used holds a piece of your customer intelligence — and they control the terms. GA4 will delete your Universal Analytics history. CRMs lock you into contracts. ESPs own your list hygiene. Migration gives it all back to you.
Duplicate contacts removed, invalid emails scrubbed, field standardisation, and null-value treatment before anything lands in your vault.
Merge fragmented records from multiple sources into single unified customer profiles — one identity across web, CRM, email, and transaction data.
Append firmographic data — company size, tech stack, revenue range, decision-maker profiles — to your migrated contact database automatically.
Consent records transferred and mapped to DPDP Act 2023 and GDPR requirements. Every contact's consent status is preserved and documented.
99.7% accuracy SLA with a formal data migration certificate on completion — documenting record counts, accuracy rates, and compliance status.
Every migration follows our structured delivery model — so your data lands clean, complete, and compliance-ready in the C360 vault.
Full audit of your current data landscape — sources, volumes, formats, quality gaps, and compliance requirements mapped before migration begins.
Source-to-destination field mapping, transformation rules, deduplication logic, and consent mapping designed and signed off.
Extraction, transformation, and loading into C360 vault. Sandbox migration first — full validation before production load.
Record count verification, accuracy sampling, duplicate check, consent record audit, and data integrity sign-off by your team.
Formal migration certificate issued. Full documentation — field maps, transformation rules, accuracy report, compliance evidence — handed over.
Migration complexity is driven by source count, data volume, and enrichment requirements. All tiers include our zero-data-loss SLA and compliance documentation.
Unlike implementation, migration involves highly variable complexity that justifies premium pricing. The technical nature of the work and the data risk involved means clients rarely negotiate — making this the most reliably profitable engagement in any partner's service stack.

Here's what every business asks before they hand over their most valuable asset.
We operate a zero-data-loss delivery model backed by a 99.7% accuracy SLA. Every migration runs in a sandbox environment first — full validation before any record touches your production vault. You sign off before go-live. We've delivered 100+ migrations without a reported data loss incident.
Yes — that's the entire point of migration. Your full contact history, engagement records, transaction data, and analytics history are brought across and stored permanently in your first-party vault. Unlike GA4, which periodically purges data, your vault retains everything indefinitely as long as you're a customer.
Every contact's consent status and source metadata migrates with them. We map consent fields from your source platform(s) to C360's consent management framework — preserving opt-in records, opt-out flags, and consent timestamps. Contacts without a valid consent record are flagged for re-consent rather than silently included.
Yes — multi-source migration is standard in our mid-market and enterprise engagements. We extract from each source independently, apply transformation and deduplication rules, and load a unified dataset into your C360 vault. Identity resolution ensures records from different platforms that belong to the same person are merged into a single profile.
Your data — including everything migrated — is yours to take. On cancellation, you receive a full export in CSV and JSON format within 7 days. All copies are deleted from Customer360 infrastructure within 30 days, with a formal deletion certificate issued. The migration fee is non-refundable as the work has been delivered, but your data never gets held hostage.
