How to Migrate Custom Fields
If the project management tool you’re migrating to supports custom fields, create all the necessary custom fields on the target system.
Go to Migration Wizard and begin setting up your migration. Connect the source and destination system. Then, you will see the page where you can select objects you want to migrate and map task fields.
Click the “Map fields” button, and you will see a form with fields available for mapping. Custom fields are located at the bottom of the form.
Note that you can only map fields of the same type. I.e., drop-down to drop-down, text to text, etc.
Map task fields and save the mapping. Then, continue with your data migration.
