Describe the issue: Is it possible to use OpenSearch Migration Assistant to upgrade to a new version of OpenSearch without using AWS services. The Migration Assistant Solution as described in Migration Assistant - OpenSearch Documentation heavily relies on AWS Services. Is it possible to use Migration Assistant without AWS. If yes, can you point to some detailed documentation regarding that.
@farman Migration Assistant is designed to migrate your cloud or on prem environment to AWS OpenSearch cluster.
The CloudFormation provided in the Migration Assistant documentation creates an instance of MA in AWS cloud.
So, it is not possible to use Migration Assistant to upgrade from one opensource version to another assuming both the instances are on-premises, i.e., they do not reside in cloud. OpenSearch Migration Assistant documentation at this link Architecture - OpenSearch Documentation says “The Migration Assistant architecture is based on the use of an AWS Cloud infrastructure, but most tools are designed to be cloud independent. A local containerized version of this solution is also available.”
