What is the best way of doing these kinds of upgradations. I think bbappend here will create problems as the SRC_URI and other variables use the PV from recipe name to fulfil some operations.

You should get a new custom layer that holds the 4.0 recipe. It is a
bad idea to use a .bbappend since you are changing the version ($PV).
Note that upgrading one recipe might require that you update some
dependencies as well. You don't need to 'disable' the old recipe, it
will be overlaid anyways.

To give you an idea, this is how we manage 'backports' for our builds:
