As I understand, adding and upgrading should be separate processes.

When you add a package, you should check if an old version of the 
package or conflicting packages exist and install package otherwise.

When you update a package, you save all dependency info, delete an old 
package, add a new one and restore dependency info. To have a recursion 
is good here (update depended packages or packages that depend on the 
package) as user choice.

There are some unclean cases there. E.g. packages with different 
PREFIXes, etc.
