I have a pkg that installs a set of applications on the user's system. This pkg is already in the market and users are using it. But now I have a set of pkgs that installs the same applications. The problem is the the previous version used just one pkg to install all the applications, but now I have a separate pkg for each of these applications. Now if a user has a older version of the app and then he installs the new pkgs then the preinstall script in the new pkg will remove the old version of the app before installing the new one. If this is not done then instead of replacing the whole app, the new pkg creates a merge of old and new app. So the final app will contain some traces of old app as well as new app. It seems to do a union of the two versions. Anyways this is not a huge problem as such since this can be handled by deleting the old version. The bigger problem is that if a user runs the older pkg then it will do the same thing. Now I cant change anything in the pkg that is already out there. So the question is how do I solve this backward compatibility issue? I have some ideas where I can prohibit the old pkg from been installed by creating a dummy receipt of the old pkg with a higher version than the one that is shipped. This will work. But I was wondering if there is a better solution than this.
