When more than one ActiveTransfer instances share the same database(ActiveTransfer Group), this property specifies the remote server alias for the other nodes. These remote server aliases are defined in the Integration Server Administrator portal. This information is used to synchronize different assets like VFS, Post Process Action, Scheduled Actions across all nodes in the group.

For example: mft.group.aliases=remote server alias 1,remote server alias 2,remote server alias 3
