Possible Issues in Upgrading from Drupal 4.66 to Drupal 4.7
Depending on the theme that was active in the live setup when you ran the backup, if you do not have the same theme in the themes folder, you may end up with a blank screen. To fix this, copy the themes and theme engines folder into the new web folder.
The front_page module in particular was causing the new installation to display a blank page. I noticed this by looking in the watchdog report in the existing installation in the root of the web folder and there was an error message as shown below.
<!-- begin content -->| Type | php |

after adding this module from the old installation, everything was working exactly as in the old installation
- I went back into the modules folder and removed all the other modules that do not come with the base installation (reducing chances of a conflict after the upgrade)
- Point the 4.7 installation to the copied database and run the update script at .../update.php
- 4.66 should be automatically detected and the upgrade process will begin
- After about 1 minute or 30 seconds of processing (it seems longer when you are praying not to see an ugly error message + it will get struck at around 80%)
