Adding new option while keeping SavedVars

Heya,

I've got an addon which uses SavedVariables. Now I want to add a new variable to the SavedVars and have the users keep their old settings.

Example old variables

Code:

defaults = {
    useDummy = false,
    startValue = 500
}

db = ZO_SavedVars:NewAccountWide("MyAddon_SavedVars", 1, nil, defaults)

Example new variables

Code:

defaults = {
    useDummy = false,
    startValue = 500,
    beAwesome = true
}

db = ZO_SavedVars:NewAccountWide("MyAddon_SavedVars", 1, nil, defaults)

And then I use the db variable with LibAddonMenu-2.0

When I give the new version to a user with old SavedVars they get an error. When I reinstall it, it works.
So for existing users the db variable does not include the new beAwesome value.

I have read about SavedVariables versioning here here https://www.esoui.com/forums/showthr...avedVars%3ANew
But then you would overwrite all existing SavedVars which is not what I want.

Is there a way to add a new variable and keep the old user settings?
