I am about to embark on upgrading a Drupal 6.16 site to 6.22. I have only recently taken on the existing (6.16) site and I'm still finding my way around a bit. There are a couple of things that I find a bit worrying:-
There's no UPGRADE.txt file in Drupal core, I've unpacked the one in the 6.22 tar archive though so I can work from that. It seems fairly straightforward if a bit complex.
When logged in as administrator on the site I can't see the Home » Dashboard » Site building » Modules page, though I can get to it by entering the URL directly into my browser's address bar. Is there some sort of configuration option that would enable/disable this? If not how do I get it back?
The UPGRADE.txt file step five says "Disable all custom and contributed modules.", how does one know which modules are custom and contributed? Is there any easy/automated way of remembering which modules are enabled so that one can turn on all the right ones again after the upgrade? Or does one just print out the web page and do it manually?
