I check, or ask the user.
I think that my questions is more of "how to do this" then who/when to
do this. I think we can agree that if my databases changes between
version and I wish to allow my users to continue running with their
existing data I need to provide some method for them to upgrade their
scheme while not loosing their data.
Pointers on the above would be very welcome.
Thank you.
Perhaps providing migration/conversion/update scripts as part of your
new RPM that the user is then instructed to run manually?
I guess this could potentially mean things won't work correctly if the
udpate happened automatically and the user wasn't around.
