In the past I had been disappointed with the upgrade process between
getpaid 0.6.1 and 0.7.0 because after the upgrade all my orders were
deleted and I could no longer add buyable items to my shopping cart.
I think I have found the solution to these problems. The important
steps seem to be deleting 'utilities' from the cascade list in
beforeUninstall(), and in not reinstalling intids (a utility) if it is
already installed. The problem with not being able to add items to the
cart went away after I removed getpaid.discount (which I was not using
anyway) from my buildout. I am using revision 2034 of the
getpaid.buildout trunk.
I am also using GetPaidStore.
Thanks,
Daniel Holth
