- Determine where the discrepancy originates. This could be from the source data, the migration process itself, or the destination system. - Evaluate how widespread the discrepancy is. Is it an isolated incident or part of a larger pattern? - Assess the quality of both the source and destination data. Look for issues like missing values, format inconsistencies, or duplicate records. - Document the resolution steps taken to fix the discrepancies for future reference. - Conduct a reconciliation process to ensure that the migrated data now aligns with the source data. - Keep all stakeholders informed about the discrepancies, their potential impact, and the actions taken to resolve them.

Puedes guiarte con 5 pasos: 1. Debes de identificalas y debes dar prioridad, clasifica las discrepancias según su gravedad 2. Revisa las reglas de negocio entre sistemas para asegurar alineación. 3. Automatiza validaciones para detectar inconsistencias. 4. Resuelve manualmente con el equipo en casos complejos. 5. Lecciones aprendidas, documenta y aprende de los problemas y soluciones. Este enfoque minimiza errores y facilita futuras migraciones.

Navigating unexpected discrepancies during a data migration can be challenging, but here are some effective strategies to address these issues: Conduct a Thorough Analysis: Start by identifying the specific discrepancies. Compare the source and target data to understand the extent and nature of the issues. Review Data Mapping: Check your data mapping and transformation rules. Ensure that all fields are correctly mapped and that any necessary transformations are applied consistently. Consult Documentation: Refer to any existing documentation regarding the data structure and business rules. This can help clarify any misunderstandings about the data.

It would depend on what data migration method is being adopted for migration. Depending on that we need to see if we can fix the issues during the migration or we let the migration get completed and then access the data issues & how much discrepancy is there and the possible fix. Also we need to understand if the data issue is due to the application feeding the data into the source while the migration is in progress. We may need to stop the data migration and the application feeding the data in source and re-run the migration. That’s one way. Otherwise we need to pause the data migration & research further into the cause of discrepancy.

During a data migration, unexpected discrepancies should be swiftly managed by pausing the process to assess the issue's impact, investigating logs and data to identify the cause, and applying quick fixes or workarounds as needed. If data integrity is at risk, roll back or isolate affected data while continuing the rest of the migration. Communicate with stakeholders throughout, keeping them informed on the issue and resolution timeline. Once the root cause is corrected, resume migration after testing in a controlled environment. Post-migration, validate data consistency and document the incident to refine processes and prevent recurrence, ensuring a more resilient migration approach.
-
When unexpected issues arise in data migration, start by identifying what the problem is—whether it’s missing data, formatting, or duplicates. Document everything, find the cause, and apply a fix. Test to make sure it works without causing new problems, and keep your team updated on any changes. Automate checks to catch future issues and, if possible, have a backup plan in place to minimize disruptions.

- Antes de iniciar uma migração seja ela parcial ou total, é de grande importância realizar backup total da aplicação seja ela uma single page ou mesmo um grande sistema corporativo. Primeiramente deve-se criar uma infraestrutura de teste que simule o ambiente real, promover essa migração nesse ambiente e testar se a mesma funcionou realizando consulta aos dados já gravados e aos gravar novos dados explorando os diferentes tipos de dados inclusive os que constam da nova atualização, uma vez confirmada que a aplicação encontra-se estável informar as novidades aos usuários. Caso não só retornar ao último backup válido e informar a equipe de desenvolvimento os problemas observados.

1,I will read the message 2,find the solution online based code errror 3,A.if it not big problem im not budge it 3,B.if im not find anything ask my friend for fixing that 3,C i will check data format and export and check the format again 4,fix the problem

Descobrir a origem é essencial, se for algo definitivo corrige-se o problema, porém é preciso saber o que causou a mudança e igualmente importante: por que todas as áreas não foram notificaras da mudança. Se existe uma fallha processual a ser corrigida, ou apenas a técnica. De outra forma nada impediria do mesmo ocorrer repetidamente.
