A mapping of old registry values which will be copied to new values. The old
value location must start with a valid hive name, followed by a key name, and
end with the value name. The source location must be separated from the new
parameter name by a -> symbol.

This setting allows to carry over settings from obsolete client installations to
newer versions of the client which may store the same information in other
locations.

For example:

  HKEY_LOCAL_MACHINE\\Software\\GRR\\certificate -> Client.private_key
""")
