I was trying to do some real work until I found out that my retardo-blog has been having some issues with PHP. This opened up a giant can of worms because now I want to move off of my shared host.
Get latest version of drupal.
Copy the important directories from the old version
cp -r ../original/files .
cp -r ../original/sites .
mysqldump -u -p databasename > backup_drupal_X.XX.sql
mysql -u -p databasename < backup_drupal_X.XX.sql #restore
Swap in updated code
mv blog drupal-BACKUP
mv drupal-X.XX blog
Update and migrate system
Now update your modules.
Run update.php again for each module. It’s OK to update the modules in bunches.
