What are the option for asset migration between AEM instances?

There are cases where we need to move assets across AEM instances. This may occur when we have multiple asset repositories and as part of merging assets we may have to move them into one single instance. While moving assets we have to consider various factors like asset metadata, asset versions, Tags w.r.t assets all moved and validated.

The overall size of asset is another consideration while selecting any tools to migrate assets. Below given few tools which can be included in our consideration while we go for asset migration.


-Replication Agent
By configuring replication agent, we can migrate assets across AEM Instances

-Vault Remote Copy

Jackrabbit vault offers a simple method to copy nodes between repositories.

This can be used for bulk assets.

-Grabbit

Grabbit provides a fast and reliable way of copying content from one Sling (specifically Adobe AEM) instance to another.
Grabbit creates a stream of data using Google’s Protocol Buffers aka "ProtoBuf". Protocol Buffers are an extremely efficient (in terms of CPU, memory and wire size) binary protocol that includes compression.

This is one of the Adobe recommended solution & can be considered for bulk assets movement.

-Crx2Oak

Crx sync option  - tools provided by Adobe while upgrading AEM or for migration of crx data.
This is one of the Adobe recommended & can be used for bulk Assets

-S3 Asset Ingestor

This is part of ACS AEM Commons .It pulls files from an Amazon S3 bucket instead of the local file system. You can load a directory of assets into AEM very easily with this tool. Because of the ability to overload a server with assets, this tool only appears for the “admin” user right now.
