Hi Great Engineer,
I have challenge to migration MySQL 5.7 VM to AWS Aurora MySQL 5.7, and this VM not in AWS so it’s cross Data Center, we are concentration how to minimize bandwidth usage when we transfer the data, anyway Database Size now around 1TB.
Current Database topology on existing VM with 1 Master and 4 Slave and we have plan to migration with DMS tools from AWS, But AFAIK the DMS doesn’t support to make master to master from Aurora Mysql to Mysql VM.
On the development env, we used dump restore and replication with native replication M to S from VM to AWS with format .sql and successed because the database size just more than 1GB so it’s makesanse we used manual replication because we already trying to replication with DMS but DMS just create meta table only not include table atributes like (index, foreign key, default value) although it worked but not recomemeded if use on Production, after that we try to only dump schema from source and restored to Aurora MySQL but there’s many table error and mismatch when DMS validated.
I need a lot of input and inspiration as well as ideas from your experiences
