Migrate from Nielsen Marketing Cloud to Nutshell

Discovery and migratability audit

We audit the source Nielsen Marketing Cloud tenant to identify all migratable objects: Consumer Profiles (with field inventory), Audience Segments, Campaigns, Data Sources, Reports, and Media Plans. We run a pre-migration data audit that simulates export sequences on a sample of records, validates encoding consistency, and identifies any profile records that relied on device graph linkage. We deliver a written migratability report that specifies what maps to Nutshell Contacts, Companies, and Deals, what maps to Notes, what is delivered as CSV data export, and what has no migration path. This report is the scope baseline before any data moves.

Nutshell schema preparation

We configure the Nutshell destination tenant: creating custom Contact fields for audience segment membership and Nielsen source attribution, creating custom Deal fields for campaign metadata and budget, and setting up any required Contact Lists that correspond to Nielsen Audience segments. We validate the Import2 connection to Nielsen's structured export format before loading. We coordinate with the customer's Nutshell admin to ensure the migration user has sufficient write permissions and that any required Nutshell plan features (custom fields, multiple pipelines) are active on the destination account.

Consumer Profile export and Contact mapping

We run Nielsen structured file exports in rolling time windows to extract Consumer Profile records. Each export batch is validated for row count, encoding consistency, and required field presence (email or phone as dedupe key). We apply a field-level transform that maps Nielsen profile fields to Nutshell Contact standard fields, assigns the profile's organization to a Nutshell Company record (creating it if not present), and writes audience segment membership to the appropriate custom field on Contact. Device graph linkage and third-party enrichment attributes that have no Nutshell field are either dropped or written to a supplementary CSV.

Audience segment and campaign mapping

We extract the Nielsen Audience segment definitions and map them to Nutshell Contact custom fields or Contact List memberships. Active Nielsen Campaigns are mapped to Nutshell Deals with campaign metadata (name, status, targeting criteria) preserved in custom Deal fields. We document the campaign schedule and channel assignment as Tasks attached to the corresponding Deal. We deliver a separate campaign inventory spreadsheet listing all Nielsen campaigns, their activation channels, and scheduling data for the customer to rebuild in Nutshell's task model.

Data Source and report inventory export

We export the data source configuration registry (name, type, connection parameters, last sync date) and attach it as a Note to the most recently created relevant Contact record. Available report structure and historical campaign performance metrics are exported as CSV files and delivered alongside a written analytics inventory that recommends a BI tool (Google Looker Studio, Power BI, or Metabase) for rebuilding key Nielsen attribution dashboards. The report CSV is not loaded into Nutshell native reporting; it is delivered for the customer's analytics team to connect to a BI tool via Nutshell's API or CSV export.

Nutshell import via Import2 and validation

We load all prepared Contact, Company, and Deal records into Nutshell via the Import2 integration. We run a sample migration first, validate record counts and field mapping, and request approval for the full migration. After full load, we run a reconciliation check comparing Nutshell record counts to the source Nielsen export counts and spot-check 25-50 records for field accuracy. We deliver a final migration report with record counts per object, any unmapped fields, and the location of supplementary CSV exports.

Cutover, handoff, and post-migration inventory

We freeze writes to the Nielsen tenant during cutover and run a final delta export of any records modified during the migration window. We enable Nutshell as the system of record for the migrated data. We deliver the data source inventory, campaign rebuild inventory, and analytics rebuild inventory as written documents for the customer's team. We do not rebuild Nielsen media plans, audience activation configurations, or adaptive learning models inside Nutshell; those are separate implementation work. We support a one-week post-migration window for reconciliation issues raised by the customer's team.
