Can we use AWS DMS homogenous migration from PostgreSQL v13 to v16

0

I am looking at the possibility of using AWS AWS DMS homogenous migration for PostgreSQL to create an instance on Version 16.* from the existing version that is on 13. Both instances will be in AWS RDS for PostgreSQL. Is it a feasible approach? What are the issues I might run into. It is a 17+ TB instance.

According to the documentation, source and target version does not have to be identical: "Your target data provider can be an Amazon RDS DB instance or an Amazon Aurora DB cluster. Note that the database version of your target data provider must be equal or higher than the database version of your source data provider." https://docs.aws.amazon.com/dms/latest/userguide/dm-data-providers-target.html

This is the supported scenario for DMS homogeneous migration. But 17+ TB migration size is quite big so recommended approach is dividing this migration to several migration tasks with max 5TB using the selection rules.
