Unless you are migrating to an S3 bucket, you should copy the binaries manually, however, there are external tools that can help you with that. For example, for Azure Blob you should use AzCopy.
If you are planning to use an S3 bucket, then there are 2 options to migrate the binaries.
We can either copy the filestore to the S3 bucket in the existing instance and then continue with the migration process (option A), or we can copy binaries to the S3 bucket after the new instance is set up (option B).
Option A:
In order to migrate to the S3 bucket in the existing instance, you should refer to our wiki page, Migrating Your Filestore to S3.
In this process, we are utilizing the Eventual Binary Provider for the Automatic Filestore Migration.
Option B:
Migrating the binaries to the S3 bucket after we have installed the new Artifactory instance, requires copying the binaries manually to the bucket and is out of JFrog scope.
However, it can be easily achieved using AWS CLI .
