The Fear That Keeps You Stuck
Every rental company that has been running for more than a year has the same concern about switching software: what happens to our data? You have thousands of equipment records, years of client history, project archives, invoices, serial numbers, and maintenance logs. The thought of starting from scratch is paralysing, so you stay on a system you have outgrown because migrating feels too risky.
It does not have to be that way. We have migrated companies from other rental platforms and various homegrown spreadsheet systems. Every migration follows the same process, and none of them required starting over.
Two Migration Paths
There are two ways to get your data into NexusRMS: API migration and CSV import. Most companies use one or both depending on what their current system supports.
API Migration
If your current platform has an API, we can connect directly and pull your data across automatically. You provide your API credentials, we map the fields, and the system transfers your equipment, clients, crew, projects, invoices, suppliers, and venues in bulk.
API migration is the cleanest option because it preserves relationships between records. Your equipment stays linked to the right categories, clients stay connected to their projects, and serial numbers maintain their maintenance history. The mapping is handled with a visual field mapper so you can see exactly what goes where before anything transfers.
CSV Import
If your current system does not have an API — or you are migrating from spreadsheets — CSV import handles everything. Export your data from your existing system as CSV files, upload them, map the columns to NexusRMS fields, and import. The system validates everything before importing so you can catch issues like duplicate serial numbers or missing required fields before they become problems.
CSV import works for any source system. We have migrated companies from Excel, Google Sheets, and custom databases. If you can export it to a CSV, we can import it.
What Gets Migrated
A full migration covers everything you need to continue operating without gaps:
- Equipment — Every item with serial numbers, categories, purchase prices, hire rates, weight, dimensions, and custom fields. Accessories and consumables included.
- Clients — Contact details, billing addresses, payment terms, notes, and communication history.
- Crew — Staff and freelancer profiles, certifications, skills, rates, and contact details.
- Projects — Historical and upcoming bookings with equipment allocations, crew assignments, and timelines.
- Invoices — Past invoices with line items, payment status, and amounts for financial continuity.
- Suppliers — Supplier details for purchase orders and sub-hire tracking.
- Venues — Venue details with addresses and technical specifications.
- Stock levels — Current quantities for bulk-tracked items.
The Process Step by Step
Migration is not a one-click process, but it is not the months-long ordeal people imagine either. Here is what a typical migration looks like:
- Export or connect — Either export CSVs from your current system or provide API credentials for direct connection.
- Field mapping — Map your existing fields to NexusRMS fields using the visual mapper. Review the preview to check data looks correct.
- Validation — The system checks for duplicates, missing required data, and format issues. You get a report of anything that needs attention before import.
- Test import — Run the import against a test environment first. Check that records look right, relationships are preserved, and nothing is missing.
- Production import — Once you are happy with the test, run the import against your live environment. This typically takes minutes, not hours.
- Verification — Spot check key records. Confirm equipment counts match, client details are correct, and historical data is accessible.
A Real Migration Example
One of our early migrations was a company moving off their previous rental platform. They had three years of data, over 2,000 equipment items, and 400 active clients. Their main concern was losing the connection between equipment serial numbers and their maintenance history.
We ran the migration using CSV export. The equipment import preserved every serial number with its full history. The client records came across with all their project history intact. The whole process from first export to verified production import took less than a week, with most of that time spent on the company reviewing the mapped data rather than on the technical transfer.
Running Both Systems in Parallel
We always recommend running your old and new systems in parallel for two to four weeks. Create new bookings in NexusRMS while keeping your old system available for reference. This gives your team time to learn the new workflow without the pressure of having no fallback.
Once you are confident that everything is in NexusRMS and your team is comfortable, you switch off the old system. There is no hard cutover date and no moment where you are flying blind.
The Real Cost of Not Switching
Migration takes effort, but it is a one-time cost. The cost of staying on software that does not fit your business is ongoing — every week, every month, every year. Double bookings, missed invoices, manual workarounds, and frustrated staff are not going away. They are getting worse as you grow.
If data migration is the only thing stopping you from switching to software that actually works for your business, it should not be. The process is proven, the data transfers cleanly, and you do not lose a thing.
