So now that the Zen Upgrade has achieved about 95% of the old site appearance the 80-20 rule says move on to the Modules upgrade.
- First task is to uninstall Image and all the associated modules. Then delete their folders in sites/all/modules. Except ImageCache and ImageField won’t uninstall, preventing Image API and FileField from being uninstalled too. (Leave ImageCache and ImageField uninstalling in session overnight. But it still ended up as ‘White screen of Death’!) Thinking back I believe I should have uninstalled and deleted all the D6 unwanted after I’d deactivated them before upgrading to D7. Looking now like a big mistake. May need to go for a re-run! 🙁
And by rolling back the VM to Snapshot D6 Step 1-5 I proved this to be true. Using uninstall on all the Image and related modules worked fine before the upgrade. - Replace old (D6) ACL, Book Access and Forum Access folders in sites/all/modules folder with new (D7) copies. Run https://c-n-u.eu/wp/update.php to update them in the database. These completed successfully. Then activated ACL, Book Access and Book Access UI, but Forum Access requires the Chain_menu_access Module installing and activating to be activated.
- Replace old (D6) Views folders in sites/all/modules folder with new (D7) copies. Run https://c-n-u.eu/wp/update.php to update them in the database. These completed successfully. But before Views and Views UI can be activated Ctools needs to be downloaded, installed and activated, so do so.
