Data migration services for a planned system change
Changing software should leave your team with records they can find and use. Gateflow prepares and transfers agreed business data, then checks the result with your team before the old system is retired.
Data migration support from Gateflow
Gateflow is an IT company in Frankfurt that implements data transfers and connections between business applications. The migration assignment covers a defined source, destination and set of records. About Gateflow explains the wider service offering. Your team provides the business decisions, while Gateflow prepares the technical steps and records what needs approval.
Data inventory before the first export
A source inventory separates current records from history, attachments and information that can remain in an archive. Gateflow checks available exports and relationships between objects, such as customers and orders. Your team decides which information the new system needs. This helps identify missing related records and unnecessary history before the transfer.
Field mapping for the target system
Field mapping defines more than matching column names. Dates, currencies, required values and customer identifiers may follow different rules in the target application. Gateflow documents those differences and the treatment of incomplete entries. Where several systems change together, migration project leadership can coordinate dependencies separately from the practical data-transfer work described here.
Trial migration with representative records
The first import uses a sample that includes difficult cases as well as ordinary records. Gateflow checks how the destination handles missing identifiers, attachments and conflicting values. Your users review the imported information in the application, not only in an export. Findings become changes to the mapping or decisions for the data owner.
Migration cutover and changes during transfer
The cutover plan states when source changes stop, how the final export is identified and who releases the target system. If work must continue during transfer, the scope needs a method for collecting later changes. Gateflow documents that sequence so a test import is not confused with the final business data.
Migration checks before business acceptance
Record counts alone cannot show whether customers, transactions and attachments still belong together. Gateflow compares agreed totals and relationships, records rejected entries and tests selected business cases. The broader data migration and system integration service includes these acceptance steps. Your data owner reviews exceptions before deciding whether the transferred information is ready for use.
Migration rollback and access to the old system
Before the final transfer, the team agrees what would trigger a return to the previous system and who can authorize that decision. Backups and source exports must remain accessible for the agreed period. Gateflow records any limits to rollback, including changes already entered into the new system that need separate handling.
Data migration handover and next steps
You receive the agreed mapping, import procedure and test findings, including outstanding exceptions. The handover identifies who maintains later transfers and where the source exports are stored. The explanation of how Gateflow works sets out how scope and acceptance are agreed. Record relationships, attachment handling and the agreed trial rounds determine the implementation effort. Send the source and destination systems and your intended change date to discuss the work.
Discuss your data migration
Gateflow prepares and transfers the agreed business records, then checks the imported data with your team. You will receive the field mapping and migration findings showing transferred records and exceptions that still need a decision.
