Overview

What this migration involves

Migrating from Bloomr to Nutshell centers on a fundamental step up in platform maturity and API transparency. Bloomr covers core CRM objects without publicly documented API endpoints or schema references, which creates uncertainty for technical teams that need verifiable export and integration capability. Nutshell provides a documented REST API covering CRM records, people, and products, making the migration path concrete rather than exploratory. We begin every Bloomr engagement with live API probing to confirm authentication method, available endpoints, pagination behavior, and rate limits before we commit to a timeline. Contacts, accounts, and deals map 1:1 to Nutshell equivalents. Activity records (calls, emails, meetings, tasks) migrate via Nutshell's Bulk API with parent-record lookup resolution. Custom fields discovered during data profiling transfer to typed Nutshell custom fields. Bloomr workflows and automations are not exportable; we deliver a written inventory of every automation with a recommended Nutshell workflow equivalent for your admin to rebuild.

Why teams make this switch

Two sides of the same decision

Leaving

Bloomr

What's pushing teams away

  • Limited platform recognition — very few third-party reviews or community discussions make independent validation difficult.
  • No documented API — absence of public API documentation concerns technical teams about export and integration capability.
  • Scalability uncertainty — no visible enterprise tier or multi-user feature set in public materials.
  • Support responsiveness — a minority of G2 reviewers cite delays or limited support options.
  • Integration ecosystem unclear — no documented connections to common tools like Zapier, Make, or Outlook.

Nutshell

What's pulling them in

  • Lowest cost entry point among mid-market CRMs—Foundation plan starts at $13/user/month, making it accessible for teams validating CRM fit before committing.
  • Integrated sales automation and email sequencing on Pro plans without requiring a separate email marketing platform, per verified Capterra reviews.
  • Consistently praised for intuitive interface and fast onboarding, with case studies reporting 100% team adoption rates within initial deployment periods.
  • Strong customer support responsiveness cited across G2 reviews, with dedicated support tiers available on Enterprise plans.
  • Native integrations with WhatsApp, Facebook Messenger, Instagram, and Slack reduce reliance on third-party middleware for common communication channels.

Object mapping

How Bloomr objects map to Nutshell

Each row shows how a Bloomr object lands in Nutshell, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Bloomr

Contact

maps to

Nutshell

Person (Nutshell CRM Contact)

1:1
Fully supported

Bloomr Contacts map directly to Nutshell Person records. We transfer name fields (first_name, last_name), email address, phone number, and any custom fields discovered during profiling. The Person record is created before any related Account to satisfy the lookup dependency. Bloomr's contact-level custom fields migrate to Nutshell custom fields created during schema design, with field types matched to Nutshell's supported types (text, number, date, picklist, checkbox). Email addresses serve as the dedupe key during import to prevent duplicate Person records.

Bloomr

Company/Account

maps to

Nutshell

Account

1:1
Fully supported

Bloomr Company records map to Nutshell Account. We transfer company name, domain, industry, size, address, and any custom company properties. The Account record is created before Person records so that the Account lookup on Person is satisfied at insert time. Bloomr's domain field becomes the Account Website field if present. Custom company properties discovered during profiling migrate to typed Nutshell custom fields on Account.

Bloomr

Deal

maps to

Nutshell

Deal

1:1
Fully supported

Bloomr Deals map to Nutshell Deal records. We transfer deal name, value, stage, owner assignment, expected close date, and associated contacts. Bloomr stage values are mapped to Nutshell stage values during transformation, and if Bloomr uses a custom stage set, we create matching stages in Nutshell before migration. Deal owner resolves by matching the Bloomr owner email to a Nutshell user provisioned before the Deals phase begins.

Bloomr

User/Team Member

maps to

Nutshell

User

1:1
Fully supported

Bloomr User records map to Nutshell User accounts. We resolve owners by email match across Contact, Account, and Deal records. Any Bloomr User without a matching Nutshell User goes to a reconciliation queue for the customer's admin to provision before record import resumes. Owner assignments on Deals and Contacts cannot proceed until this step is resolved because OwnerId is a required reference on most standard objects.

Bloomr

Activity: Call

maps to

Nutshell

Activity (Task with Call subtype)

1:1
Fully supported

Bloomr call records map to Nutshell Activity entries with type preserved as Call. Call duration, disposition, and timestamp transfer to corresponding Activity fields. Activity ordering is preserved by setting the activity date to the original Bloomr timestamp. We load call records via Nutshell's Bulk API for volumes over 5,000 records to avoid REST timeout issues.

Bloomr

Activity: Email

maps to

Nutshell

Activity (Email record)

1:1
Fully supported

Bloomr email engagement records map to Nutshell Activity records with type Email. We transfer subject, body, timestamp, direction (sent/received), and the linked contact reference. If Bloomr exposes email thread threading data, we preserve it in a custom field for context. Email activity migrates via Bulk API when volume exceeds 5,000 records.

Bloomr

Activity: Meeting

maps to

Nutshell

Activity (Event record)

1:1
Fully supported

Bloomr meeting records map to Nutshell Activity entries with type Meeting. We transfer meeting title, scheduled date and time, duration, location, and attendee list (linked contacts). Meeting ordering and timestamps are preserved. If Bloomr provides attendee details per meeting, we link those contacts to the Activity record.

Bloomr

Activity: Task

maps to

Nutshell

Activity (Task record)

1:1
Fully supported

Bloomr task records map to Nutshell Activity entries with type Task. We transfer task subject, description, due date, status, and assigned owner (resolved via User mapping). Task completion status migrates directly. If Bloomr tasks are linked to specific Contacts or Deals, we resolve those Lookups and link accordingly.

Bloomr

Custom Fields

maps to

Nutshell

Custom Fields

lossy
Mapping required

Bloomr custom fields on any standard object (Contact, Account, Deal) are discovered during data profiling before migration begins. We create equivalent typed custom fields in Nutshell for each discovered field, matching the Bloomr field type to Nutshell's supported types. Multi-select or checkbox fields in Bloomr become Nutshell picklist or checkbox fields. The custom field mapping is validated in test migration before production begins. Custom field naming preserves the Bloomr label for admin recognition unless a naming conflict exists in the destination.

Pair-specific challenges

  • Bloomr API access must be confirmed before we commit a timeline

    Bloomr has no publicly documented API endpoints, authentication method, or export schema. Every Bloomr migration begins with live API exploration to probe authentication (API key, OAuth, or none), available endpoints, pagination behavior, and rate limits. If the API is inaccessible or returns insufficient data, we fall back to CSV export from the Bloomr UI, which cannot capture activity history, custom field schema, or bulk record sets at scale. We do not commit a migration timeline until API probing completes and the data extraction path is confirmed. This discovery step adds one to two weeks to the project schedule.

  • Attachment and file storage access is unconfirmed

    File attachments linked to Bloomr Contacts, Deals, or Activities may not be accessible via export. The absence of documented API or export endpoints means we cannot verify whether attachments are stored in Bloomr's database, as separate files, or referenced externally. We do not include attachment migration in standard scope until file access is confirmed through API exploration. Any attachments stored within Bloomr must be identified and exported separately from the UI if the API does not expose them. We flag this gap during discovery so the customer can decide whether to manually export attachments outside the migration scope.

  • Workflows and automations do not migrate as structured data

    Bloomr's automated sequences, workflow rules, and lead routing logic are not accessible via any documented export mechanism. Teams moving from Bloomr with established automations must manually document and rebuild these in Nutshell. We do not migrate automation as code. We provide a workflow audit template during scoping to capture Bloomr automation logic, and we deliver a written inventory of every discovered automation with a recommended Nutshell workflow equivalent for the customer's admin to rebuild post-migration. This gap affects any team that relies on automated lead routing, task creation, or email triggers.

  • Activity history migration depends on API exploration outcome

    The ability to migrate calls, emails, meetings, and tasks from Bloomr is directly tied to whether the API exposes engagement records. Without a confirmed API, activity history cannot be extracted programmatically and does not migrate. We flag this during discovery. If the API does not expose activity data, the customer chooses whether to proceed with record migration only (Contacts, Accounts, Deals) or manually export activity history from the UI, which is time-intensive for large volumes. We do not overpromise activity migration for Bloomr until the extraction path is confirmed.

Migration approach

Six steps for a successful Bloomr to Nutshell data migration

  1. API exploration and data profiling

    We begin every Bloomr engagement by probing the live API to confirm authentication method (API key, OAuth, or none), enumerate available endpoints, measure pagination behavior, and identify rate limits. Simultaneously, we profile the data structure to identify all standard objects (Contacts, Accounts, Deals, Users), any custom fields on each object, and engagement records available for migration. This step produces a written API confirmation report and a preliminary data inventory that determines the extraction path for all subsequent phases.

  2. Schema design and field mapping

    We design the Nutshell destination schema based on the discovered Bloomr field set. This includes creating custom fields in Nutshell for each Bloomr custom field discovered during profiling, mapping Bloomr field types to Nutshell field types, designing the Account and Contact lookup relationship, and configuring Deal stages. We validate the schema in Nutshell before any production migration begins. If Bloomr's API does not expose activity records, we document this gap and scope activity migration as a manual export fallback or exclude it from the project scope.

  3. User provisioning and owner reconciliation

    We extract every distinct Bloomr User referenced on Contact, Account, Deal, and Activity records and match by email against the Nutshell destination account's user list. Any Bloomr User without a matching Nutshell User goes to a reconciliation queue for the customer's admin to provision before record import resumes. Owner assignments on Deals and Contacts cannot proceed until this step is resolved because OwnerId references are required on most standard objects in Nutshell.

  4. Test migration and validation

    We run a full migration into the Nutshell destination using production-like data volume and validate record counts, field mapping accuracy, and lookup resolution before production migration begins. The customer's point of contact spot-checks 25-50 random records against the Bloomr source and signs off the mapping before production migration starts. Any field mapping corrections, stage value adjustments, or schema changes happen in this phase, not in production.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Accounts (from Bloomr Companies), Persons (Contacts with AccountId resolved), Deals (with OwnerId and linked Persons resolved), and Activity history (via Bulk API for volumes over 5,000 records with parent-record lookup resolution). Each phase emits a row-count reconciliation report before the next phase begins. We freeze Bloomr write access during cutover and run a final delta migration of any records modified during the cutover window.

  6. Cutover, validation, and automation inventory delivery

    We enable Nutshell as the system of record after the final delta pass and deliver the written automation and workflow inventory to the customer's admin team. We support a one-week post-migration window where we resolve any reconciliation issues raised during the first week of live use in Nutshell. We do not rebuild Bloomr automations as Nutshell workflows inside the migration scope; that work is handled by the customer's admin or a Nutshell implementation partner using the inventory document we deliver.

Most Bloomr migrations complete in four to seven weeks. The first one to two weeks cover API exploration, data profiling, and schema design. The production migration phase runs one to two weeks depending on record volume and whether activity history migration is in scope. Activity history above 5,000 records extends the production phase because we load through Nutshell's Bulk API with parent-record lookup resolution. Migrations requiring extended API exploration or multi-pass data validation move to eight to twelve weeks.
