Ideally, Chandler would check for updates, and when it finds there is one:

That works fine if the user is managing the Chandler installation
manually. However, that won't work for packaged distributions once
Chandler goes into the repostories and users install it with a package
manager. There won't be upgrade check in a packaged application, because
the upgrade is handled by the package management system.

Neither Mac nor Windows are affected by this. It seems to me that having installation/upgrade/migration paths that reflect the realities of each platform we support is a must.

actually the package systems allow for pre and post install steps where we can run export routines (in the pre) and then run import routines in the post install.
