SO from what i understand and maybe I am wrong but if one wants to go from Oracle to AWS Aurora Postgres it requires a GGhub setup. On that hub you would need to install it a couple different ways.
GG installed on source and on hub install GG for postgres. Then just put a replicat on hub to AWS postgres.
No GG on either source or target. On the hub you put GG for Oracle and GG for postgres and then build extract in oracle version of GG and replicat on Postgres GG version. Do I understand that correctly? Thanks in advance.
