What moves from Salesforce

Each of these is written against the real API rather than a generic model, which is where the depth comes from.

Accounts, contacts, leads and opportunities

Leads land as people. A lead already converted in Salesforce is not imported twice — it resolves onto the contact it became, so tasks and notes pointing at the lead still find their record.

Custom objects

Any queryable __c object. The field Salesforce marks unique or idLookup becomes the dedup key, and lookup fields resolve to the Attio object you pointed that lookup's target at.

Both note systems

Classic Notes and enhanced ContentNotes, the latter read with their document links so each note lands on the right record rather than on the user who wrote it.

Tasks and events

Tasks become Attio tasks; events become Attio meetings.

Field history

Optional, read from each object's history table so a closed-won date from last year still reads as last year.

And on every migration

Relationships, resolved in a second pass

Records are created first and linked second, so a deal finds its company no matter which order they arrived in. A link whose other end never made it is reported as a skipped row naming what it was waiting for.

Dedup against what is already in Attio

People match on email, companies on domain, custom objects on the unique key you designate. A matched record is updated in place, so running the same migration twice never leaves you two of anything.

A sample run before the real one

Cap the import at the first 50 records, read the result, then promote it to a full run with one click.

Cancel that leaves zero trace

Every record, note, task, meeting, list entry, attribute and select option this migration created is deleted or archived in reverse order. Whatever was in your workspace before is never touched.

5 things that don’t move

Each is a ceiling in an API, not a feature we haven't written yet. You'd find them on day two, so read them now.

ContentNotes your user cannot see

Doesn't move

Without the org permission "Query All Files", Salesforce returns only the notes shared with the connecting user and reports that as the whole set. The connection checks your permission sets and warns before the run; an org that will not report them cannot be checked at all.

History on long text fields

Doesn't move

Salesforce returns a null new-value on every edit of a field over 255 characters, which would import as a series of clears. Those fields are skipped and named in the summary.

Polymorphic lookups

Doesn't move

A field like WhatId can point at several kinds of record at once. No single Attio attribute can hold that, so it is left for the mapping review rather than guessed.

Emails

Doesn't move

Attio asks migration tools not to import them — its own inbox sync covers email far better than a one-time copy would, and it keeps working after the migration.

File attachments

Doesn't move

Attio publishes no endpoint for writing files onto a record, so there is nowhere to put them.

Move 50 Salesforce records first. Then decide.

Free at any record count. Nothing is written to Attio until you have approved the structure and the field mapping.
