How long does switching from rexx HR actually take?

An evening for most accounts. The export from rexx HR is the slow step - the import side runs in minutes once the field mapping is settled. Larger teams (50+ seats with custom field schemas) sometimes split it across two sessions: import first, reorganise the next day.

Will I lose data when I switch?

Nothing structural. The CSV/JSON export from rexx HR preserves the data: records, fields, history, and attachments come over intact. What doesn't transfer is anything tied to rexx HR-specific UI metadata (custom views, saved searches, in-app annotations) - those don't sit in the export, they sit in the source product's UI. Plan an evening to rebuild your most-used views once you're in.

What about my existing rexx HR subscription?

Run both side-by-side until you're confident, then cancel rexx HR from their side. We don't lock you in - export from KI BMS is one click in account settings, same as import.

Is the import path free?

The import button is open on every plan, including the free tier - we don't paywall the way out of a competitor. The data going in still has to fit your plan's per-type quotas (the free-tier caps are listed on /sales); paid plans raise those caps. If you're moving a large set, check the caps first or write to /support and we can advise.

Can I get help with the switch?

Yes. Write to /support - both founders see those threads directly. Reply within a working day. For the field-mapping itself we typically resolve things in one or two exchanges; if your dataset is unusually large or rexx HR's export shape is unfamiliar, we'll say so up front.

KI BMS is what people use when rexx HR stops fitting. Below is the honest side-by-side - same product surface, different posture: hosted in Germany, no third-party trackers, one honest price - plus the migration mechanics that decide whether the switch lands in an evening or in a quarter.

At a glance

rexx HR is a full HR suite (employee files, payroll integration, recruiting, onboarding, talent management) with German legal grounding and enterprise experience. KI BMS is only the recruiting module - but productive faster, KI pre-sort in the free tier, monthly cancellation. Need a real HR suite? Pick rexx. Want a dedicated ATS? Pick us. Common reality: rexx HR for files, KI BMS for the pipeline.

Switching

What moving from rexx HR actually looks like

The switch goes in three rough phases: export from rexx HR, import into KI BMS, and reorganise what came over. Most people allocate an evening for it. The export side is where the time goes - rexx HR hands you a CSV/JSON dump and the field mapping isn't always obvious; once that's resolved the import is a couple of minutes. We don't paywall the import path or pretend it's a pro-only feature, and you can run both side-by-side while you decide.

When to pick which

Pick KI BMS when

Recruiting is the bottleneck; the rest of HR is manageable with Excel + DATEV.

You want your ATS set up in an afternoon, not a quarter.

Small to mid team (8-100 employees), not controlled by procurement.

Pick rexx HR when

200+ employees, want employee files + onboarding + payroll integration in one tool.

Procurement + works council require a mature HR suite with enterprise experience.

Talent management + training should be connected to the ATS.

When a suite makes sense - and when not

rexx HR is a mature suite running in 500+-employee enterprises for years. The value is consolidation: employee data, jobs, applications, files, performance, training in one tool, one source of truth, one audit log. Teams that need that are well served.

What suite logic doesn't do well: fast iteration, KI-first features, light setup paths. A suite has grown into an existing enterprise IT landscape; a specialist starts with the recruiting workflow as the core and makes that fast. Both logics are valid - they just fit different companies.

Where a split makes sense

In the pilot teams we know, this is the common pattern: rexx HR keeps files + payroll + onboarding (set up once, runs); KI BMS runs in parallel as the recruiting layer. The handoff is at hire: the person is created fresh in rexx HR (or migrated by CSV), the application data stays archived in KI BMS. Nobody misses the integration; the clean split is worth it.

Step by step

Export from rexx HR

Find the export option in rexx HR's account settings. Most tools provide a CSV or JSON download. Save the dump locally - that's the source of truth for the next step.

Account settings → Export / Download data

Pick the broadest format the tool offers (usually JSON)

Map fields in KI BMS

Open the import tool in KI BMS. rexx HR's field names rarely match KI BMS' 1:1; the import flags any unmapped columns so you can pair them up before anything commits.

Account settings → Import

Resolve the mapping prompts the tool surfaces

Run the import

Run the import. KI BMS shows a preview of the first parsed rows in the import dialog so you can sanity-check the column mapping + a sample of records before anything commits. If you're nervous about a large dump, import a small subset first, verify it landed the way you expected, then run the full file.

Re-create your views, tags, saved searches

rexx HR-specific UI metadata (custom views, saved filters, in-app annotations) doesn't transfer with the data export. Spend an evening rebuilding the views you used most - usually a 30-minute job once you've done it once.

Cancel rexx HR when you're confident

Run both side-by-side for a couple of weeks if you want to be sure. When you're confident, cancel the rexx HR subscription from their side. KI BMS keeps your export option self-serve in account settings - no lock-in either direction.
