CRM-migrering: Legacy-system till HubSpot
Zero-downtime migration av ett växande säljteam från ett legacy-CRM till HubSpot - med anpassad fältmappning, telefoniintegration och fullständig teamutbildning.
Why this migration was hard
Legacy CRM lock-in
Det befintliga CRM-systemet hade år av anpassade fält, arbetsflöden och informell kunskap inbäddad. Ingen ren exportväg fanns.
Complex data mapping
200+ custom fields, nested contact-company relationships, and activity history that needed to survive the migration intact.
VoIP-beroende
Säljteamet var beroende av VoIP-systemet för samtal. Telefoniintegrationen behövde fungera från dag ett i HubSpot - inget glapp tillåtet.
Team adoption risk
Säljteamet hade använt det befintliga CRM-systemet i flera år. Förändringsmotstånd var den största risken i projektet.
How we executed
Data mapping framework
Built a comprehensive field-by-field mapping document. Every legacy CRM field was mapped to a HubSpot property, with transformation rules for data types and picklists.
Custom migration scripts
Python-based ETL pipeline that extracted, transformed, and loaded data in batches. Dry-run mode let us validate before the real cutover.
Telefoniintegration
Konfigurerade VoIP-HubSpot-integration med native-koppling samt anpassade webhook-hanterare för samtalsloggning, inspelningslänkar och aktivitetssynk.
Phased training program
3-phase rollout: power users first, then team leads, then full org. Each phase included hands-on workshops and cheat sheets.

Lärdomar
Map everything before you move anything
We spent the first 2 weeks purely on discovery and mapping. That upfront investment meant zero surprises during migration.
Dry-run migrations are non-negotiable
We ran the full migration 3 times in a sandbox environment. Each run surfaced edge cases that would have caused data loss in production.
Train the trainers first
Getting 5 power users fluent before the full rollout created internal champions who could support their teams organically.
Activity history matters more than you think
Sales teams live in activity timelines. Migrating call logs, email threads, and notes was harder than contacts - but critical for adoption.
Plan for the telephony gap
Phone integrations always have edge cases. We built a fallback logging system that captured calls during the 2-hour integration switchover.
“The migration was seamless. Our team walked in on Monday to a fully working HubSpot with all their data, call history, and workflows intact. Zero complaints - that never happens with CRM changes.”
