larger size db export from rackspace

Question

I am planing to migrate my Db from rackspace to AWS. The current db has around 50GB of size. So how can i export this Db from rackspace without downtime.Or any other solutions like direct migration from rackspace to AWS RDS

Answer 1

Amazon provides multiple options in the RDS docs. Have you read them?

My preference would be to set up replication between your Rackspace instance and a new RDS instance. This will minimize your downtime: when you're ready you shut down your applications, reconfigure them to use the new database, and you're done.

I recommend planning for at least three attempts, since replication can be tricky the first time you set it up. Even if you get the replication right on the first try, I strongly suggest that you bring up a test environment and do a complete regression test of your app, before repeating the replication for your production cutover.

Answer 2

Yes, You can easily achieve migration without any outage using DMS services given by Amazon. I used DMS for migration from Company Hosted Environment to RDS.
