Alright I did not catch this " ... with new OS" from your original post.
I saw "Take offline full backup (PG_DATA folder alone) using OS
command" and "Restore offline full backup (PG_DATA folder alone) using
OS command" and assumed like to like on the OS, my mistake.

Logical replication would not have issue with this as that is one of
it's use cases. The question now becomes whether that is the quickest/
most efficient way to do this.
That depends on:
1) What is the size of database(s) you are dealing with?
2) What sort of downtime can you afford?
3) EC2 --> EC2, are they the same region?
