Overview

What this migration involves

Migrating from UKG Ready to Crelate is a transition from a full HCM suite to a dedicated applicant tracking system. UKG Ready functions as the system of record for employees, their compensation and benefits enrollment, time and attendance, and recruiting pipeline data. Crelate is purpose-built for talent acquisition workflows and manages Candidates, Job Orders, Placements, and hiring team Activities. We migrate the recruiting-adjacent data (employee records as contacts, candidates, job postings, and interview history) and flag that payroll, benefits, accrual balances, time entries, and pay statement data have no native equivalent in Crelate and require manual handoff to HR or payroll systems. Workflow configurations, HR Action Request templates, and Benefits workflows do not migrate; we deliver a written inventory for the customer's admin to rebuild in Crelate's workflow builder.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Two sides of the same decision

Leaving

UKG Ready logo

UKG Ready

What's pushing teams away

  • Users consistently cite the unintuitive interface and steep learning curve as a reason to seek alternatives, with nested menus and poor context help slowing daily workflows.
  • Pay calculation errors, particularly around overtime, shift differentials, and accrual balances, drive churn among organizations with complex pay rules or union-represented workforces.
  • System reliability issues including crashes, slow performance, and mobile app failures have led to payroll delays and employee grievances in high-profile cases like Kroger.
  • Organizations with more than 1,000 employees often find UKG Ready lacks the depth needed for complex multi-entity, global, or highly customized HCM requirements.
  • Configuration complexity around pay rules, timesheet profiles, and workflow routing creates ongoing administrative burden that many teams find unsustainable without dedicated support.

Object mapping

How UKG Ready objects map to Crelate

Each row shows how a UKG Ready object lands in Crelate, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

UKG Ready

Employee

maps to

Crelate

Contact

1:1
Fully supported

UKG Ready employee records map to Crelate Contact. We preserve first name, last name, email, phone, address, hire date, employment status, and manager relationship. The manager relationship in UKG maps to the manager field on Crelate Contact. HR Custom Fields on the Employee object migrate as Crelate Custom Properties with field type validated against Crelate's supported property types (text, number, date, dropdown) during scoping. Employment status values (active, inactive, terminated) map directly to Crelate Contact status.

UKG Ready

Employee (recruiter or hiring manager reference)

maps to

Crelate

User

1:1
Fully supported

UKG Ready employees who participate in recruiting (hiring managers, interview panelists, HR recruiters) map to Crelate User records. We match by email address. Any UKG Ready employee referenced as a hiring manager without a corresponding Crelate User goes to a reconciliation queue for the customer's admin to provision the account before activity import begins.

UKG Ready

Base Compensation

maps to

Crelate

Contact Custom Property

lossy
Fully supported

UKG Ready Base Compensation records (salary amount, pay type, effective date) have no native equivalent in Crelate's ATS schema. We store the most recent compensation data as text-based Custom Properties on the Crelate Contact (e.g., Annual Salary, Pay Type, Compensation Effective Date) and flag during scoping that this is reference data only, not a native compensation tracking capability. Full compensation history does not migrate.

UKG Ready

Accrual Balances

maps to

Crelate

Not migrated

lossy
Mapping required

UKG Ready accrual balances (PTO, sick leave, and other leave types) have no equivalent in Crelate's ATS schema. Accrual tracking is an HR system function, not an ATS function. We document accrual balance snapshot values for each employee in a written reference sheet for the customer's HR admin to maintain in their payroll system. No accrual data moves into Crelate.

UKG Ready

Cost Center

maps to

Crelate

Department or Contact Custom Property

lossy
Fully supported

UKG Ready Cost Center data maps to Crelate Department if the organizational structure is relevant to talent acquisition (hiring team ownership, requisition routing). We confirm during scoping which Cost Center field holds the primary organizational unit, since third-party integrations specifically reference the third Cost Center field regardless of its label. Crelate Departments are flat groupings; Cost Center hierarchies in UKG flatten to a single Crelate Department assignment per Contact.

UKG Ready

Position (Enterprise tier)

maps to

Crelate

Department or Team

lossy
Fully supported

UKG Ready Position data (available in Enterprise tier only) defines job title, department, and reporting structure. We map Position titles to Crelate Department or Team for requisition ownership and candidate routing. Position-based reporting hierarchies do not have a Crelate equivalent and are documented in the written organizational handoff rather than migrated.

UKG Ready

Benefits Plans

maps to

Crelate

Not migrated

lossy
Mapping required

UKG Ready benefits enrollment data, carrier connections, and plan types do not migrate to Crelate. Benefits administration is an HR system function outside ATS scope. We document the existence of benefits enrollment records per employee as a written reference sheet for the customer's HR admin to maintain in their payroll system. No benefits data moves into Crelate.

UKG Ready

Pay Period Profile

maps to

Crelate

Not migrated

lossy
Fully supported

UKG Ready Pay Period Profile definitions (weekly, bi-weekly, semi-monthly payroll cycles) have no equivalent in Crelate. We document the pay period configuration in the written handoff as relevant for HR administrators who may need this context when managing offer letters or start dates within Crelate. No pay period data migrates.

UKG Ready

Candidates (UKG Ready Recruitment module)

maps to

Crelate

Candidate

1:1
Fully supported

If UKG Ready contains candidate records from its recruitment module, these migrate to Crelate Candidate. We preserve all application stage history, source information (referral, job board, direct), and any existing candidate score or rating. Pipeline stage names from UKG map to Crelate pipeline stages during the stage alignment step of configuration. Candidate attachments migrate as file links in Crelate.

UKG Ready

Job Posting / Job Requisition

maps to

Crelate

Job Order

1:1
Fully supported

UKG Ready job postings and requisitions map to Crelate Job Orders. We preserve job title, job description, department, location, employment type (full-time, part-time, contract), and the open or closed status. The recruiting pipeline stage from UKG (e.g., Open, On Hold, Filled) maps to Crelate Job Order status. Candidate count per job and source breakdown migrate as reference data on the Job Order.

UKG Ready

Interview and Hiring Activity

maps to

Crelate

Activity

1:1
Fully supported

UKG Ready interview activities, evaluation scores, and hiring workflow actions migrate to Crelate Activity records. We preserve activity type (interview, assessment, screening call), date, duration, participant list (linked to Crelate User or Contact by email), and any scoring or rating data. Activity ordering is preserved by timestamp. Bulk API chunking handles large activity volumes to avoid timeout during import.

UKG Ready

Workflow Configurations

maps to

Crelate

Not migrated

lossy
Mapping required

UKG Ready workflow configurations (HR Action Requests, Benefits workflows, Time Approval workflows, Performance Review workflows) are destination-dependent and do not transfer 1:1 to Crelate. We do not migrate workflows as code. We deliver a written inventory of every active UKG Ready workflow with its trigger, conditions, and actions for the customer's admin to rebuild in Crelate's workflow builder. HR Action Request workflows require particular review because Crelate's workflow model differs significantly from UKG's.

UKG Ready

Company

maps to

Crelate

Company

1:1
Fully supported

UKG Ready companies mapped as clients or customer organizations (distinct from the employing organization) migrate to Crelate Company records. We preserve company name, address, industry, and any associated contacts or candidate relationships. If UKG Ready Company records serve exclusively as the employer organization, they are handled within the Employee-to-Contact mapping instead.

Pair-specific challenges

  • UKG Ready compensation and accrual data has no native Crelate equivalent

    UKG Ready is an HRMS that tracks salary, pay type, compensation change history, PTO and sick leave accrual balances, and benefits enrollment. Crelate is an ATS with no native compensation, accrual, or benefits objects. We store current salary as a text-based custom property on Crelate Contact, but compensation history, accrual balances, and benefits data do not migrate. We flag each of these as a written reference entry for the customer's HR admin rather than silently omitting them. If the organization relies on UKG for accrual tracking (common for hourly workforces), a separate accrual management solution is required post-migration.

  • HR custom field types require validation before import

    UKG Ready supports HR custom fields on the Employee object with types including text, date, and picklist. Crelate uses its own custom property system with a different type model. We validate field types during scoping and flag any UKG custom field type that Crelate does not natively support. If a UKG custom field uses a type Crelate cannot represent, we store the value as text and document the type difference in the mapping specification. Custom field value mapping (e.g., picklist value labels that differ between systems) is handled as part of the scoping-phase value mapping exercise.

  • Cost Center field selection requires explicit confirmation

    UKG Ready supports multiple Cost Center fields per employee, but third-party integrations specifically map to the third Cost Center field regardless of its label. We confirm during scoping which Cost Center field holds the primary organizational unit used for recruiting team routing or requisition ownership in Crelate. If Departments in Crelate will be sourced from UKG Cost Centers and the wrong field is used, candidate and requisition routing will point to the wrong team. We validate Cost Center field selection during the sandbox migration phase before production import begins.

  • UKG Ready recruiting pipeline stages may not match Crelate stage names

    UKG Ready configurable recruiting stages (Application Received, Phone Screen, First Interview, Second Interview, Offer, Hire) often have different names from Crelate's default pipeline stages. We perform explicit stage name alignment during configuration, creating Crelate pipeline stages that match the UK's stage names and probabilities. If the customer's UKG stages include custom stages not present in our standard stage library, we add them as custom stages in Crelate before migration. Stage alignment errors at migration time cause candidates to appear in the wrong pipeline stage in Crelate, requiring manual correction after go-live.

  • UKG workflow configurations do not migrate to Crelate

    UKG Ready workflows for HR Action Requests, Performance Reviews, Benefits Administration, and Time Approvals have no equivalent in Crelate's ATS workflow model. Crelate's workflow engine is designed for recruiting automation (candidate stage advancement, email triggers, task creation) rather than HR operations automation. We do not migrate workflows as code. We deliver a written inventory of every active UKG Ready workflow with its trigger, conditions, actions, and recommended Crelate equivalent for the customer's admin to rebuild. HR Action Request workflows require particular review because they often reference compensation, benefits, and accrual data that Crelate does not store.

Migration approach

Six steps for a successful UKG Ready to Crelate data migration

  1. Discovery and tier audit

    We audit the source UKG Ready account across tier (Start, Core, Plus, or Advanced), employee volume, candidate record count, job order history, HR custom field count, Cost Center configuration, and any active recruiting workflows. We confirm whether the UKG Ready recruitment module is in use and whether candidate records exist. The discovery output is a written migration scope document specifying what migrates to Crelate, what migrates as a reference note, and what is excluded with justification.

  2. Scope definition and field mapping specification

    We define the mapping specification: employees to Crelate Contacts, candidates to Crelate Candidates, job postings to Crelate Job Orders, and activities to Crelate Activities. We confirm which Cost Center field is the primary organizational unit. We validate HR custom field types against Crelate's supported property types. We perform stage alignment between UKG recruiting stages and Crelate pipeline stages. We document all UKG data that does not migrate (compensation history, accrual balances, benefits, pay period profiles, workflow configurations) with written reference handoff instructions.

  3. Sandbox migration and reconciliation

    We run a full migration into a Crelate sandbox using production-like data volume. The customer's talent acquisition lead reconciles record counts (Contacts in, Candidates in, Job Orders in, Activities in), spot-checks 20-30 random records against the UKG source, and validates that Cost Center-to-Department mapping is correct. Stage alignment is confirmed by checking that candidate records appear in the correct pipeline stage. The customer signs off the sandbox results before production migration begins.

  4. Destination configuration

    We configure Crelate destination objects: creating Departments from UKG Cost Centers (with the confirmed field selection), adding HR custom fields as Crelate Custom Properties, creating or aligning recruiting pipeline stages to match UKG stage names and probabilities, and setting up Crelate User accounts for any UKG employees who participate in recruiting. Custom property field types are validated against Crelate's type model before any data loads.

  5. Production migration in dependency order

    We run production migration in dependency order: Crelate Users first (for any active hiring managers not yet provisioned), then Contacts (from UKG Employees), then Candidates, Job Orders, Activities, and Companies. Each phase emits a row-count reconciliation report before the next phase begins. Compensation data (stored as Contact custom properties) loads after the base Contact record is confirmed. Activities load via chunked batch processing to handle volume without timeout.

  6. Cutover, validation, and workflow rebuild handoff

    We freeze UKG Ready recruiting writes during cutover, run a final delta migration of any records modified during the migration window, then enable Crelate as the recruiting system of record. We deliver the UKG workflow inventory document to the customer's admin team with Crelate equivalent recommendations. We support a one-week hypercare window where we resolve any reconciliation issues raised by the recruiting team. We do not rebuild UKG workflows in Crelate; that is a separate engagement or an internal admin task.
