You can transfer values and connections from one container to another using the Transfer Attribute Values option. Maya copies the values from any identically named published attributes from the source container to the target container.
To transfer attribute values between containers
All identically named attribute values are transferred from the source container to the target container.
Transfer attribute values options
Maya provides a few container-specific options for transferring attributes. You can access these options from the Edit > Transfer Attribute Values > .
You can use the Relationships option to re-parent external objects parented to the published anchors of the source container to the published anchors of the target container given that both published anchor names match.
You can also use the Rename option to give the target container the source container’s name (the source container is automatically renamed with an Orig suffix).
Both these options are useful when you want to completely replace the source container in your scene with the target container.
