问题
I am having some trouble upgrading my dnn 7 website. I am upgrading from 7.0.5 to 7.0.6 and I have previously tried upgrading to 7.1.0 but I ran into errors, now I have left over files from the previous upgrades left in the instal/authSystem install/provider install/module folders.
Can I empty these folders before copying over the upgrade package over the current version? Should they be empty? or how can I figure out what the default contents should be for the install folder when upgrading.
回答1:
As to your question, simply empty the INSTALL folder and get the INSTALL folder from the upgrade package.
Really though, you should take your backup from before you attempted the upgrade, and take all of the files from that backup, and start with those, essentially starting with a clean folder, copy the files into that folder from the backup, then perform the upgrade.
