Migrate Self Managed MongoDB from EC2 to EKS

Question

I have installed MongoDB community edition v7.0.1 in one of the EC2 instance with 64GiB EBS Volume for Data & log. Now we are moving to micro service architecture and need to migrate the MongoDB instance from EC2 to AWS EKS with Persistent Volume setup. Was looking at online options, but not sure on how to migrate the existing data in EBS volume to PV/PVC in EKS with no downtime ? Does AWS Database Migration Service suits here ? Any leads will be highly appreciated. Thanks!

Answer

Indeed AWS DMS does support [using MongoDB as a source](https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.MongoDB.html) so that is one option.

You should also consider [AWS DocumentDB](https://aws.amazon.com/documentdb/faqs/) as that is fully managed MongoDB compatible service from AWS, or even consider [MongoDB Atlas](https://aws.amazon.com/marketplace/pp/prodview-pp445qepfdy34) if AWS DocumentDB is not a good fit.
