# Migration from DT v1.0

> [!CAUTION]
> Note: DT v1.0 has been deprecated.

To assist users migrating from DT v1.0, this page provides a mapping
between old and (where available) new fields and files.


We suggest that you first work through the [getting
started guide](https://developers.google.com/bid-manager/dtv2/getting-started), this will ensure than you can retrieve your data files. Next,
check out the [release
notes](https://developers.google.com/bid-manager/dtv2/reference/release-notes#changes-from-dt-v1) for differences in how the two systems behave. Finally, use the data
below to help map fields in those files from the previous version.
