Can a .pkg replace an application bundle with a different name?

Question

In the previous Mac release of our software, we foolishly put the major version number in the application bundle name: /Applications/CellProfiler2.0.app

Now we are about to release version 2.1. Is it possible to have pkgbuild make a .pkg package that installs the new version as /Applications/CellProfiler.app but removes the old /Applications/CellProfiler2.0.app?

Answer 1

It is; and in fact, You have, as we see it, two options here:

1) Use pre-install scripts in the pkg to either detect your old version and ask the user to remove it, or remove it yourself (or first just rename the directory to be without the 2.0)

2) Package your installer in a DMG, and run the installer as a separate file altogether, and do either of the above.
