Quick answer

Migrate into Bombora with a list inventory, field map, pilot import, dual-run week, and CRM sync validation — then cut over only when the pod trusts the contacts. Prove one segment before you move the whole book of lists and sequences.

Bombora migration takeaways

Lists are the product — B2B intent-data specialist best known for Company Surge® topic-level buying signals that help sales and marketing teams prioritize in-market accounts — typically layered onto CRM/ABM stacks rather than used as a contact database. A migration that moves rows but breaks suppressions or owners will burn credits and trust.
Pilot before bulk — One seller’s book or one ICP segment first — fix mapping before volume.
CRM stays the system of record — Research names Salesforce, HubSpot, Marketo, 6sense, and Demandbase on the Bombora side — confirm CRM sync and the connectors your daily loop depends on.
Watch packaging during cutover — Researched plans: Company Surge, Intent Data Platform. Never invent list prices here — confirm seats, credits, and quote terms on /pricing/bombora/.

Ask vendors to show the workflow live, not just describe it.

1Inventory source objectsLists, sequences, dialer books, suppressions, owners.
2Sign off the field mapTitles, emails, phones, owners, do-not-contact.
3Run a pilot importOne segment; fix mapping before bulk.
4Dual-run one weekBombora is write-path; old tool is read-only.
5Validate with the podSpot-check contacts and CRM sync before cutover.

1. Inventory lists and map fields before any import

Bombora migration diagram 1. — Map meanings and owners before volume into Bombora.

Inventory contacts, accounts, sequences, dialer books, suppressions, and owners in the source tool.
Map each critical field to Bombora (and to CRM where sync will write).
Decide archive-only fields — do not invent destinations for junk.
Remap departed owners to living users before volume. Worked example: an 8-person B2B outbound pod discovers 14% of open sequence steps still owned by a departed AE; they remap those owners in the sheet before any Bombora import.

2. Pilot one segment — then scale

Bombora migration diagram 2. — Fix mapping on one Bombora segment before you scale.

Choose one seller’s book or one ICP segment (tens to low hundreds of records).
Import into Bombora, then spot-check emails, phones, titles, and suppressions.
Run one sequence or dialer session from the pilot set.
Confirm CRM received the activities before approving bulk. Worked example: an 8-person B2B outbound pod pilots Sam’s mid-market list into Bombora, finds two title mappings wrong, fixes the map, and only then schedules the full import.

3. Dual-run one week with a hard write rule

Bombora migration diagram 3. — One dual-run week is enough if Bombora is truly the write path.

Declare Bombora the write path for new lists and outreach.
Old tool becomes read-only history — no new sequences there.
If anyone starts a new campaign in the old tool, restart the dual-run week.
End the week with seller sign-off on 20 random contacts. Worked example: an 8-person B2B outbound pod prints the rule on Slack: “New outreach only in Bombora.” Two violations restart the clock; week two is clean and they cut over.

4. Cut over after CRM sync and pod validation

Bombora migration diagram 4. — Cut over to Bombora only after the pod trusts contacts and CRM sync.

Validate CRM sync for creates and activities.
Freeze legacy write access.
Archive or export legacy lists you still need for audit.
Schedule the first post-cutover usage review. Worked example: an 8-person B2B outbound pod cutovers only after Priya and Sam each confirm five contacts and their last outreach appear correctly in CRM from Bombora.

5. Inventory what must move into Bombora

List users, historical records, templates, and integrations that must survive migration. Mark nice-to-have exports you can leave behind.

Worked example: ABM and enterprise sales teams that need third-party intent layered onto CRM/ABM stacks migrates active records only and archives the rest as read-only exports.

6. Run parallel cutover with a rollback path

Keep the old system read-only until Bombora passes non-admin proof. Name a rollback owner and maximum parallel window.

Worked example: ABM and enterprise sales teams that need third-party intent layered onto CRM/ABM stacks caps parallel run at two weeks with daily checkpoint notes.

7. Verify counts and permissions after import

Reconcile user counts, role permissions, and a sample of migrated records. Research lists Salesforce, HubSpot, Marketo, and 6sense for Bombora. Confirm which are native vs API before go-live.
