read till the end please.

We chose to use DMS because it was well supported by the GOV.UK PaaS and we could also get support from AWS. If we were doing a PostgreSQL to PostgreSQL database migration in the future, we would invest more time in trying alternative tools such as pglogical. DMS potentially added more complexity, and an unfamiliar replication process than what we may have found with other tools. This backs up what AWS say themselves on PostgreSQL to PostgreSQL migrations.

it doesn't come across as an ad to anything.
