Migrate from another CRMMigrate from Nutshell to SellioCRM
Connect your Nutshell account, preview what will happen, and bring everything over with relationships intact. Nothing is written without your confirmation, and every import can be undone.
Enter your Nutshell account email and API token and you are connected right away. You get people, companies, Nutshell leads as deals (they have a stage, value and won or lost), calls, meetings, tasks and notes, pipelines with their milestones, users, and the files on each record.
- contacts
- companies
- deals
- activities and history
- pipelines and stages
- users (owners)
- attachments
🔄 sync by full sweep
What the API does not expose- A separate leads module (in Nutshell the "lead" is the deal)
API key or credentials pasted on screen
Connection with a Nutshell API key plus the account email (authentication uses both).
Files are read record by record in the final phase; on large databases that step takes longer and runs in the background.
Connect your Nutshell account using whatever it offers (authorization inside the CRM, an API key, or your own app). The credential is stored encrypted and can be revoked at any time.
Click Discover data: SellioCRM reads which objects exist in Nutshell, how many records each one has and which fields, including custom ones. Nothing is imported in this step.
Map the fields: AI proposes where each Nutshell field should go, with a confidence score. A field with no equivalent can become a new field with one click. You review and approve.
Review the preview: a sample from the source goes through the approved mapping and shows what would be created, updated and skipped, without writing anything. A readiness card warns you if a key field was left without a source.
Start the import and follow the progress. When it finishes, read the field-by-field check, turn on continuous sync if you want to keep mirroring Nutshell, and undo everything with one click if needed.
Switching CRMs is usually the most expensive and risky part of any change: exporting spreadsheets, reconciling fields, losing history. In SellioCRM, migrating from Nutshell is a guided wizard. You connect your account, the system discovers your objects, fields and even custom fields on its own, proposes the mapping with AI help, and shows how many records would be created and updated before anything is written. The import runs in the background and every record keeps the identity it had in Nutshell, so re-importing or syncing never duplicates. When it finishes, a field-by-field check shows what arrived and what was left out, and one click undoes everything if you want to start over.
Preview before writing
The preview applies the approved mapping to a real sample and shows how many records would be created, updated and skipped, with examples. Nothing is written in this step.
Re-importing never duplicates
Every imported record keeps the key it had at the source. Running again, fixing the map and importing once more, or leaving sync on always updates the same record instead of creating another.
Full undo
On the import card, Undo removes the records the migration created, returns the updated ones to their previous state, and deletes the files imported with them. It is your safety net.
Field-by-field check
When the import finishes, the system compares, for every mapped field, how many records had a value at the source and how many ended up with a value here. Total loss, partial loss and what was deliberately left out show up in the Imports list and in your notifications.
Attachments last, at the right pace
Files come in the final phase, after records, history, pipelines and owners. If the daily API quota runs out, the phase pauses, the screen says until when, and it resumes on its own without touching what already came in. Up to 20 files per record and 25 MB per file; anything beyond that is counted, never silently lost.
Do I need to export spreadsheets from Nutshell?
No. You connect your account and SellioCRM reads the data straight from the Nutshell API. No CSV and no manual reconciliation.
Verliere ich Historie oder Beziehungen?
No. Companies come in before contacts, and contacts before deals, so every deal points to the right company and contact. Activity history lands on the record it belonged to.
What about the custom fields I created in Nutshell?
Discovery reads every field at the source, custom ones included. On the mapping screen each one can go to an existing field, become a new field with one click, or stay out, and the summary shows how many were left without a destination.
Was, wenn ich etwas falsch importiere?
Before writing, the preview shows what would happen. Afterwards, one click undoes the whole import. If you would rather fix the map and import again, nothing duplicates: records are updated through their link to the source.
Can I migrate gradually without stopping the operation?
Yes. After the first load, turn on Keep in sync: from time to time SellioCRM brings what changed in Nutshell and updates the matching records. You work in both and flip the switch when you are ready.
Kostet das extra?
Migration is part of the CRM, which is free. It stays free as long as your infrastructure usage always stays below US$ 20 per month; beyond that, you pay for the month's usage, just like the rest of the product.
