What are data migration services?
+
Data migration services move data from one system, database, or storage platform to another. They include planning, extraction, cleansing, mapping, transformation, loading, validation, and cutover, so the new system starts with complete and accurate data.
What are the main types of data migration?
+
The main types are database migration, application migration, storage migration, cloud migration, and business process migration such as moving to a new ERP or CRM. Many projects combine more than one type.
What is the difference between data migration and data integration?
+
Data migration is a one-time move of data from an old system to a new one, after which the old system is usually retired. Data integration keeps two or more live systems exchanging data continuously.
What is ETL in data migration?
+
ETL stands for extract, transform, load. Data is extracted from the source, transformed to match the structure and rules of the target, and loaded into the new system. It is the core technical step in most migrations.
How long does a data migration take?
+
It depends on the number of source systems, data volume, and data quality. A single database with clean data is measured in weeks, and an ERP or multi-system migration with trial runs is measured in months. We confirm a realistic timeline after the assessment.
How much does data migration cost?
+
Cost depends on the number of source systems, data volume, data quality, transformation rules, downtime tolerance, and compliance needs. We provide a scoped estimate after a free consultation and a migration assessment.
Will there be downtime during the migration?
+
Most migrations need a planned cutover window, which we schedule outside your busy hours. Where downtime must be minimal, we use a phased or incremental approach so that only the final changes move during the switch.
How do you make sure no data is lost?
+
We take a verified backup before each run, run trial migrations on copies of your data, and reconcile source and target with record counts, control totals, and field-level checks. Your users also review samples before go-live.
Can you migrate data from a legacy or custom-built system?
+
Yes. We analyse the legacy database, document its structure, and build extraction scripts for it, even where documentation is missing. Data that is not migrated is archived so it stays available.
Can you migrate our data to a new ERP or CRM?
+
Yes. We migrate master data, open transactions, and the history you choose to keep, and we verify opening balances and key reports with your finance and operations teams.
Can you clean our data as part of the migration?
+
Yes. We profile the data, remove duplicates, standardise formats, and apply the rules your team approves, so the new system does not inherit old problems.
Is our data secure during migration?
+
Data is encrypted in transit, access is limited to the named project team, and confidentiality terms are agreed before you share anything. For regulated data, we agree the required controls with your compliance team first.
What happens if something goes wrong during cutover?
+
Every cutover has a rehearsed rollback route and a go or no-go checkpoint. If validation fails, we return to the old system, fix the cause, and reschedule.
Do you provide support after the migration?
+
Yes. We monitor the new system after go-live, correct data issues found in daily use, and help you archive or retire the old system.
