The best way to pass data from one CA to another is to use properties. If
your CA that consumes properties is deferred then all properties can be
passed as a string in one property that has ID as your deferred action; and
in your deferred action you retrieve that string reading CustomActionData
property. If your properties hold sensitive data you mark them as hidden
and you add attribute
msidbCustomActionTypeHideTargetto your CA
