What details are needed for Data Migration?

[Anonymous]

Hi,

What are the details we need to get from client for migrating data from existing system to new system? 

Do we need to prepare mapping sheet and if yes then what kind of details should be included in mapping sheet or we need to ask data dictionary?

Can anyone help me with the migration questions or how actually that process is done?

Thanks,

Dhara
