DMS Create Migration Project gets stuck

0

Hello everybody, I'm following the documentation to convert a database schema (here), but I'm stuck in the "Create Migration Project" step.

Form Descriptions

The first thing I've noticed in the creation form is the descriptions of "Source" and "Target": Source and Target incorrect descriptions

Source and Target

When I set the source data provider, everything seems ok: Source data provider input


But when I try to set the PostgreSQL target: Target data provider input

The only available choice is the same as the source. I tried to select PostgreSQL as Source, but I can only use PostgreSQL in the Target section.

Thanks in advance for any help!

Hi

DMS schema conversion does not support MySQL to Postgres conversion or vice versa. It's only supported for homogeneous conversion.

Source for DMS schema conversion -> https://docs.aws.amazon.com//dms/latest/userguide/CHAP_Introduction.Sources.html#CHAP_Introduction.Sources.SchemaConversion Targets for DMS schema conversion -> https://docs.aws.amazon.com//dms/latest/userguide/CHAP_Introduction.Targets.html#CHAP_Introduction.Targets.SchemaConversion

If your goal is to migrate data from a MySQL database to a Postgres database or vice versa. I would recommend simply looking at creating a DMS task and forgoing the schema conversion (https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Tasks.Creating.html). Schema conversion is required only if you have specific conversion needs.

  • Thanks for the quick response. Could you confirm for me if the form descriptions are correct?

  • Hi, sorry I didn't get what you mean by form descriptions

If you look at the first screenshot, the description of the Source and Target fields are identical. Is it correct?

As mentioned in another answer, DMS Schema Conversion is limited in source and destination. However you can use AWS Schema Conversion Tool that is a stand-alone package with more flexibility in terms of heterogeneous conversions and covers your source and destination.
