Switching CDC from SqlServer to RDS

we are planning to migrate SqlServer to RDS, is there any way to switch CDC from SQL Server to RDS and preserve CDC metadata, the reason connector " MySQL CDC Source" running in production, if we switch CDC from SQLServer to RDS, connector is going to pull the changes from the beginning which we don’t want, I’m wondering if anyone had similar issue and found a solution for this.

worst case I’m thinking , we can resume the connector after switching CDC to RDS then let all the message expire by changing retention_ms on each topic.
