How to Switch DMS Providers Without Losing Your Data

Deciding to leave your current DMS is the easy part. The harder question is what happens to years of customer records, deal history, and vehicle inventory once you sign with a new vendor. This is the sequence a switch actually follows: what your migration team exports from your outgoing system, which data classes carry over, how records get mapped and checked for duplicates on the way in, what gets reviewed before anything goes live, and why the cutover itself lands on a weekend with both systems running side by side afterward.

DealerClick's data migration team handles the extraction, transformation, and import so your staff is not doing it by hand on top of a normal deal volume. None of it requires new hardware or an IT project of your own — the work happens on the vendor side, with your team reviewing what comes over before it goes live.

Exporting Your Data from the Current System

DealerClick's migration team works directly with your current DMS provider to obtain properly formatted data exports, rather than asking your staff to pull reports by hand. On the receiving side, DealerClick accepts Excel spreadsheets (.xlsx and .xls), CSV files, vCard contact exports, and custom delimited text files using whatever separator your old system uses.

That range of accepted formats is part of what lets the extraction, transformation, and import process work from virtually any existing DMS system, rather than only a handful of supported ones.

What Data Carries Over

A DMS switch is not just an inventory transfer. DealerClick's migration process moves customer records — contact information, credit applications, and purchase history — along with vehicle inventory covering both current stock and sold units with their full history. Financial transactions carry over as well, and for dealers who carry paper on their own customers, active loans and payment schedules move with them, alongside vendor and lender information and user accounts with their role assignments.

Documents and scanned files can move too, though depending on how much paperwork your dealership has accumulated, DealerClick may bring those over separately from the rest of the data rather than in the same batch.

Field Mapping and Duplicate Handling on Import

Once your files arrive, DealerClick maps each import column to the right field using drag-and-drop mapping, with the system suggesting matches automatically based on your column headers and letting you correct anything it gets wrong. Phone numbers, names, dates, and addresses are reformatted to a consistent standard as part of the same pass, and a mapping template is saved so a repeat import from the same source does not require redoing the setup.

Before anything is written to your account, an import preview shows exactly how the data will look and flags records with formatting or data-quality problems so they can be fixed or skipped rather than imported broken. Duplicate contacts are handled the same way — you can skip them, merge them into the existing record, or create a new one — and larger imports run in the background with a completion report and a de-duplication pass once they finish, so day-to-day work is not blocked while the transfer runs.

The Weekend Cutover and Running Both Systems in Parallel

Before any of this becomes final, you review a sample of the migrated data to confirm it is accurate, rather than finding a problem for the first time after go-live. DealerClick assigns a dedicated implementation manager to walk you through that review and the rest of the setup, including the deal structures, form packs, and third-party connections your dealership actually uses, so nothing about the configuration is generic.

The migration itself typically happens over a weekend, which keeps it out of your regular selling hours. After the cutover, DealerClick keeps both systems running in parallel so your team can still pull up historical deals in the old system while they get comfortable working in the new one, rather than losing access to years of records the moment the switch flips.

What to Require from Any DMS Before You Sign — Including DealerClick

Before you sign with any vendor, ask what happens to your data the day you decide to leave. DealerClick answers that question in writing: complete data sets — customer records with full contact and deal history, inventory records current and historical, financial transactions, payment histories, and document attachments — can be exported at any time as CSV, Excel, or JSON files, formats chosen to match what other DMS platforms already expect on import.

If you ever do leave DealerClick, that export comes with a full data migration package at no additional cost, and DealerClick keeps your data on file for 90 days after cancellation so the transition is not a race against a deadline. The same standard should apply to DealerClick's CRM or any other system holding your customer data — ask before you sign what happens to it the day you leave; if a straight answer is hard to get, that is worth knowing before your own records are the ones on the line.

Switching DMS platforms is mostly a data problem, not a feature problem — the export, the mapping, the review, and the cutover are what determine whether the move goes smoothly. If your team needs help planning a switch, including staff training on the new system, DealerClick's implementation team can walk through what it looks like for your dealership.
