Currently, to move content (in my case BLPackages) from one version to another version of BSA i have to do the following:
Have an instance of BSA available with the source content in it.
Export the content. The content will now be in the version of the environment i exported it from.
Create a temporary environment of exactly the same version of BSA.
Import the content.
Upgrade the temporary BSA instance to exaclty the same version as the target BSA environment. The content is now also version-upgraded.
Export the content.
Import the content in the target environment.
An import/export function that is version neutral would save a lot of time and open up real possibilities for content sharing among users and even for a BMC Content Store where BMC can host (and sell?) BMC software in BSA format.
