Migrate RDS to Aurora MySQL with Ruby on rails Elastic Beanstalk

I have a Ruby On Rails App on Elastic Beanstalk with MySQL RDS, and I want to migrate it to Aurora MySQL, I could migrate my database and I have the new endpoint of Aurora MySQL, I first tried to connect it in my development environment to check if everything was going good, but when I try to deploy in production I got an error by elastic beanstalk "12_db_migration.sh failed.", but It does not have sense because I connected the database in development and It worked, It looks like if elastic beanstalk couldn't connect to the database, all credentials are correct. There are not pending migrations, and the error message does not have sense. Something important is that my previous MySQL version is 5.7.24 and the MySQL version of my new Aurora MySQL database is 5.7.12, but I think It doesn't matter because in development worked well.
Thank you.
okay, I could fix it, the problem was that I was written my credentials in database.yml file without using environment variables, I was testing something and I didn't use environment variables, and It looks that I cannot do that, I use environment variables in the file and everything worked.

MySQL read replica on Mac with Homebrew

I've recently started using AWS Aurora to take advantage of the improvements over standard MySQL. I have a REST API running that connects either to the main cluster endpoint, or the read endpoint if the request will only perform SELECTs. Obviously I want to test this locally so that I don't mark any routes as read only if they're not.
I installed mysql with Homebrew and have it running as a service. What I need to do now is have another mysql instance running on a different port, and then set up read replication between my original instance and the new one.
Does anyone have any idea how I go about this?

Is it possible to downgrade a AWS RDS from mysql 5.7 to lower version (say 5.6)

This is something i need to figure out, my company runs a number of prod RDS on AWS. Some of the mysql RDS run with 5.7 , i need to downgrade the mysql to 5.6 or 5.5 . Is this functionality provided by AWS.
Scenario: A mysql server already up and running with mysql version 5.7, Downgrade this to 5.6
-> If this is possible then what are the possible ways ?
-> How to do this ?
This is not something that AWS provides out of the box, however it can be solved with below 2 approaches depending on your database size and downtime that you can accept.
It might worth considering fixing application compatibility instead of downgrading DB which is more risky operation.
1. Dump, restore and switch method
Dump your currently running database with mysqldump utility. Start a new RDS instance with downgraded engine, load your dumped data into it. Switch your application to use RDS instance with downgraded engine.
2. Dump, restore, replicate & switch method
Dump your currently running database with mysqldump utility. Start a new RDS instance with downgraded MySQL engine, load your dumped data into it.
Set the new, downgraded DB instance as read replica of your old DB instance using mysql.rds_set_external_master and then start replication using mysql.rds_start_replication. Stop writes to your original DB, once the read replica catches up (you must monitor replication lag), run mysql.rds_reset_external_master which will promote your downgraded instance and turn off replication. Point your application to the downgraded RDS DB instance.
Method 2 will shorten your downtime to minimum, but is a bit more complex to execute. Here is a command reference to get familiar with to help you succeed: MySQL on Amazon RDS SQL Reference
You will find a great amount of examples in RDS documentation also - Importing and Exporting Data From a MySQL DB Instance:

How to import a mysql db into Azure sql without .net tools

We're running Linux VM's with MySQL on Azure and want to start using Azure SQL, but need to get the data from one into the other, initially.
Is there a way to dump a mysql database and then import that into an Azure sql database?
I'm on a Mac (or can be on Linux), so the .net tools won't help.
I've tried having Azure use the mysql dump. Reads it, but nope.
I've tried selecting the mysql tables from an open connection and drop them on the Azure db, also in an open connection, via Navicat. Nope.
I also tried looking for something in SQLPro for MSSQL. Nope.
Also, I'm willing to edit the mysql dump if there are minor global things to do so that Azure sql will read it.
You can:
1. Install mysql instance on windows based server.
2. Dump all your databases into there using mysql dump.
3. Use all the spectrum of microsoft tools for your goal.

MySQL mirroring on EC2

I'm running two MySQL server one on production and one on staging, both are EC2 Instance.
The same way i have two MySQL RDS Instances parallel to the production and staging.
Here want i wanted to do.
I would like to mirror the production database to the development server every few hours,
for 1. backup, 2. to run new features against the latest database changes.
I didn't find much information regarding this issue, can anyone help?
Thanks.
Additional information:
i'm running nginx on linux server, with php backend.
If you are running on RDS, you have two options.
Snapshot and restore your instance. You can automate this, but the time it make take more time the larger the DB is. Your endpoint will probably change too.
Dump the database from production, reload into development.
