Latest DMS Engine Version

Question

I am trying to find the latest DMS engine version number.

Here is what I have found: 
"When you launch a new replication instance, it runs the latest AWS DMS engine version unless you specify otherwise."
But this does not mention what the latest version number is.

Using a PostgreSQL database as an AWS DMS source says:
PostgreSQL source version 14.x - Use Aws DMS version 3.4.7 and above.
This, at least specifies that there is a version 3.4.7, but it doesn't say that is the latest number.

Today I created a DMS Replication instance with DMS endpoints.  The replication instance shows engine version 3.4.6 and I did not specify the engine version.  But it seems like there must be a version 3.4.7 because that is required when your source db is PostgreSQL version 14.x.

Where can I find the current, latest DMS engine version number?

In the AWS Console, navigate to the ****DMS ****(Database Migration Service) section using the search bar.
From the left side navigation menu , select **Replication Instances**.
Select the link to the replication instance that you want to know the version of.
The Summary section will display the version of the DMS instanceunder Engine Version heading.

Ideally it should launch latest version of DMS instance if you dont provide version. I hope you are using some automation tool which might be defaulting to 3.4.6.
If you manually input the version to 3.4.7 it should launch the required one. 
 if you use manual console way to launch a replication instance it should launch with version 3.4.7 (latest)

Hi , if you use CFN, this works fine in Resources section:

```

CdcReplicationInstance: 
    Type: AWS::DMS::ReplicationInstance
    DeletionPolicy: Delete
    Properties:  
      ReplicationInstanceClass: !Ref CdcInstanceType
      EngineVersion: !Ref CdcEngineVersion
      #Same as Subnet1
      AvailabilityZone: !Select
        - 0
        - !GetAZs ""
      ReplicationSubnetGroupIdentifier: !Ref CdcDmsSubnetGroup
```
where CdcEngineVersion is in Parameter section:

```
CdcEngineVersion:
    Description: 'dms cdc engine version'
    Default: '3.4.7'
    Type: String
```

Hi, If you use CloudFormation, use this:

I use this all the time and it works fine to reach the version of engine that you want
