Build your ERP data migration staffing plan around named owners for source data, conversion code, and business acceptance. Before you open a search, have the program manager identify who can approve a mapping change, correct a supplier record, and accept a balance difference. Give those people time in the project schedule.
Microsoft includes sourcing, cleansing, mapping, transformation, and importing among the activities that customers and implementation partners should assign in their implementation responsibilities. Use those activities to scope the work. You can then decide which employees can cover it and where you need an ERP migration specialist.
Start with the source inventory and migration scope
The migration lead should build an inventory of source systems and data objects with the functional leads. For each object, record its business owner, source location, extraction method, and target. Ask the business owner to decide which records the team will migrate and which history users will access through an archive.
Separate master data from open transactions and balances. A supplier master conversion needs different approval and reconciliation work from an accounts payable conversion. The finance owner should define the accounting cutoff; the procurement owner should decide how to handle duplicate suppliers. The technical lead should confirm how engineers will preserve relationships between those objects.
Microsoft's migration work-item fields include source and target entities, migration volume, cleansing strategy, and validation method. Capture those details before estimating staffing. Then compare the migration schedule with your ERP implementation phases so the same functional specialists have time for design reviews and conversion testing.
Assign delivery work and approval rights
The program manager should name an accountable owner for each responsibility below. One person may cover several responsibilities on a smaller project. Confirm their availability during overlapping load cycles and business testing before combining assignments.
- Migration lead: Own the object inventory, conversion schedule, dependencies, and issue escalation. Agree with the program manager on the evidence the team must produce before cutover.
- Source analyst and data steward: Profile the legacy records, investigate duplicates and missing fields, and coordinate corrections with business owners. Record who approved a correction rule and which records it affects.
- Functional lead: Define target business meaning and approve mappings with the process owner. Resolve choices such as payment terms, organizational assignments, and units of measure.
- Migration engineer: Build extraction and transformation routines, execute loads, and retain error logs. Version the code and mapping inputs so another engineer can repeat the run.
- Reconciliation analyst and business owner: Compare source and target results. The analyst investigates differences; the business owner accepts the result or requests corrections.
Have the security administrator provision migration and validation access before rehearsals. SAP explains that migration users need permissions for the migration tool and the relevant functional application, and directs teams to each object's post-processing guidance for validation. Check those requirements against your deployment in SAP's Migration Cockpit overview.
Give cleansing and mapping decisions a business owner
Ask the data steward to present a sample of source defects before hiring an engineer to resolve them. The procurement owner might approve a rule for merging supplier records while requiring separate records for different legal entities. The engineer can implement that rule after approval and retain a trace from the original records to the target identifiers.
For each transformation, have the functional lead document the source field, target field, conversion rule, and approver. Include an example input and expected output. Assign a person to resolve exceptions, with a decision deadline tied to the next load cycle.
The migration lead should review unresolved decisions with the program manager. If business owners lack time to review records, reserve their time or appoint authorized delegates before adding technical capacity. The engineer needs approved rules to finish the conversion.
Staff reconciliation before the first mock conversion
The finance and operations owners should define acceptance checks before engineers execute the first load. Specify the source extract cutoff and the target report or query the analyst will use. For an accounts payable conversion, ask the finance owner to approve comparisons by legal entity and currency, investigate unmatched documents, and record acceptance of remaining differences.
Keep technical load checks and business acceptance as separate tasks with named reviewers. The engineer accounts for rejected records and confirms rerun behavior. Business users test representative transactions using migrated data. Microsoft includes migrated-data testing and business signoff in its go-live checklist.
Retain the extract identifier, mapping version, load log, and reconciliation results for each rehearsal. Ask the migration lead to attach the business owner's approval and unresolved exceptions. The support team can use that evidence to investigate a missing document after launch.
Reserve people for rehearsals, cutover, and handoff
The cutover manager should schedule a rehearsal with the people who will execute and validate production conversion. Microsoft recommends practicing with the same data, tools, and people, and recording task owners, backups, verification steps, and rollback instructions in the cutover plan.
During the rehearsal, have engineers record extraction, load, and correction times. Business reviewers should record how long they need for reconciliation. The program manager can then reserve coverage for the full conversion window and assign the sponsor authority to approve or postpone go-live.
Before migration specialists leave, the support lead should accept the runbook, code locations, access responsibilities, and open-issue list. Name the employee who will answer data questions after cutover. Extend specialist coverage through the agreed handoff if that employee needs another supervised run.
Screen candidates against work they owned
Use the same questions for candidates competing for the same responsibility. Ask for sanitized examples or a walkthrough that protects former employers' data.
- For the migration lead: Describe a conversion you planned. Identify the dependencies, business approvers, and criteria you used to recommend proceeding or delaying.
- For the analyst: Walk through a source defect you investigated. Explain who approved the correction and how you checked affected records.
- For the engineer: Explain how you handled a partial load failure. Show how you identified rejects and prevented duplicate records during a rerun.
- For the reconciliation specialist: Describe a difference between source and target results. Explain how you traced it and who accepted the resolution.
The hiring manager should record each candidate's decisions and deliverables beside the responsibilities in the brief. Include the platform, source systems, next rehearsal date, and business reviewers available to the hire. Use Crosscheck's ERP staffing specialty to frame the search, then submit the hiring brief with the ownership gap and required handoff date.
