Salesforce Migration in Derry

Moving Derry organisations onto Salesforce, where the loading order is dictated by the relationships between records. Accounts before Contacts, Contacts before Opportunities, and every lookup needs the target to exist already — so a migration is a sequenced operation with external identifiers holding it together, not a single import.

Why this comes up

The problem

The extract was loaded object by object, half the relationships are empty, and nobody can rerun it without creating duplicates.

What you get

What we deliver

  • External IDs on every object so loads can be rerun without duplicating
  • Objects loaded in dependency order with relationships resolved as you go
  • Automation and validation deactivated during load, then reinstated deliberately
  • Data volume assessed against storage, which is charged per record
  • History and attachments migrated or consciously left behind, with a decision recorded
  • Reconciliation by count and by value once the load completes

Salesforce Migration in Derry — common questions

Why are external IDs so important?
Because they make loads repeatable. With an external identifier you can upsert — insert if new, update if present — which means a failed or partial load is rerun rather than cleaned up. Without one, every retry risks a second copy of everything.
Should automation run during migration?
No. Validation rules, flows and triggers written for user activity will reject or transform historic data, and they slow the load enough to matter at volume. Deactivate them, load, then reactivate and check what the automation would have changed.
Does storage really constrain us?
It can. Data storage is allocated by record count rather than by how much is in each record, so millions of thin historic rows consume the same allocation as substantial ones. It is worth pricing before deciding to bring twenty years of history.
How much history should we migrate?
As much as somebody will actually use, plus whatever you are obliged to keep. Teams default to everything, which increases cost and slows the project, when a read-only archive of the old system frequently serves the genuine need better.
Do you work with businesses across County Londonderry?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Derry businesses do you usually work with?
Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
Do you cover the areas around Derry?
Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
