Use Case
Data Migration Prep
Prepare old exports, spreadsheets, and business records before a platform change or system migration. Valiance Labs cleans, maps, validates, and structures the data before it enters the next system.
Why teams ask for this
Migration prep is a data preparation problem before it is a platform problem.
Teams usually look for help when a new system is ready, but the old exports are duplicated, incomplete, inconsistent, or not mapped to the new structure.
A new platform will not clean old records by itself
Duplicate accounts, stale statuses, missing values, and unclear IDs can become new-system problems if they move untouched.
Migration decisions need to be explainable
The team needs to know which records move, which fields map, which values need review, and what should be left out.
Where this shows up
Where data migration prep shows up.
The pattern appears before a team changes tools, retires spreadsheets, or moves old records into a new system.
- CRM migrations
- project management tool migrations
- spreadsheet-to-SaaS transitions
- product catalog migrations
- customer, vendor, or contact list migrations
- accounting or software imports with agreed project boundaries
- Airtable, Notion, ClickUp, Asana, or Monday transitions
- old system exports that need cleanup before a new tool
Why files get messy
What usually makes migration data messy.
Migration risk often starts in old exports and spreadsheets before the new platform is involved.
- duplicate records
- old statuses or categories
- fields do not map to the new platform
- missing required values
- inconsistent names, dates, or categories
- outdated records
- messy exports from old systems
- source IDs need to be preserved
- invalid rows need review
What the workflow prepares
What the workflow prepares.
The preparation workflow gets the source data ready for a migration vendor, import tool, or new platform workflow.
- old system exports
- CRM, contact, customer, vendor, or product lists
- project or task exports
- platform export files
- spreadsheets used as databases
- migration import templates
What changes when the workflow is structured
Old data is reviewed before it moves.
The source data, mapping decisions, and review rows are made clearer before the import file or migration handoff is used.
- old exports are cleaned before they move
- source-to-target fields are documented
- missing required values are visible
- invalid rows are separated for review
- migration-ready files are easier to explain
What you get back
Potential migration-prep outputs.
The output should help the team review what is ready, what needs mapping, and what should not move forward yet.
- migration-ready dataset
- cleaned source export
- mapped fields
- deduped records
- validation/error report
- mapping documentation
- import-ready CSV
- rejected-row list
How Valiance Labs helps
How Valiance Labs helps.
Valiance Labs prepares messy source files before migration by cleaning, mapping, standardizing, validating, and documenting what should move into the new system.
Relevant Data Preparation capabilities
Data CleansingClean duplicate, incomplete, malformed, or review-needed values inside source files.Data MappingConnect source columns and values to the structure the next workflow requires.Data StandardizationMake names, dates, fields, categories, statuses, and formats consistent across files.Data ValidationCheck required fields, duplicates, changed formats, missing values, and exceptions.Existing tools
Migration tools may already be enough.
Platform migration tools, import templates, spreadsheets, CRM importers, scripts, and migration vendors may be enough when the data is already clean and mappings are straightforward. Valiance Labs works alongside those tools when exported data needs cleanup, field mapping, duplicate review, or validation before the migration.
Use the migration path when source data is clean
If records are current, fields map clearly, and required values are present, the platform or migration vendor may not need extra prep.
Prepare first when old data carries risk
Duplicate records, stale fields, missing values, unclear mappings, and invalid rows should be resolved or surfaced before migration.
Sensitive data
Data access should match the work.
Migration prep may involve old system exports, customer, vendor, or contact records, historical records, IDs, statuses, and account data. Valiance Labs can often begin with source schema, target import structure, masked records, mapping notes, and representative invalid rows before live data is used.
Minimum necessary data
The project can focus first on the source structure, target requirements, mapping rules, and records that show the review needs.
Representative migration examples
Source and target field lists, masked records, import templates, mapping notes, and invalid-row examples can show where migration prep is needed.
Production access by agreement
If live exports are needed, the sharing method, access level, storage, retention, and handling expectations should be agreed before production files are used.
