Data migration
Data migration moves information into a new tool or structure while preserving meaning and integrity.
How it works
It requires field mapping, quality checks, rehearsals and reconciliation of totals. A cutover defines who can write and how to recover.
Hypothetical small business example
When changing CRM systems, a business can test synthetic contact imports before qualifying mappings and permissions.
Benefits and limitations
A more controlled transition with fewer missing or duplicate records.
Incomplete history, different formats and retention rules complicate transfers. A backup alone does not validate a migration.
Common question
Can migration happen without downtime?
That depends on the systems. Synchronization, conflicts and any write freeze must be estimated and tested before promising continuity.
