Transfer sites to new server checklist

Transfer sites from old host to our new server steps.

1. Create a new site with Agaric's addsite script. (Really? OK. addsite example example.org)
2. Create a database for the site. Check if it exists first
3. Download our old-server site's theme and add it to example.org/themes directory, done.
4. Check out to live-sites, done.
5. Copy over or create the empty files directory, done.
6. Copy over the plain settings.php from test-sites (we missed this so our settings.php is currently in live-sites/default).
   NOTE: If a test-to-live script can do this only if files and settings.php do not exist that would be fantastic
7. Export our old-server site's database, change the table prefixes to our standard (find-and-replace in a text editor), and import via phpMyAdmin into database created in step 2. We ought to delete cache_ data (but not the tables themselves) in this process.
8. Edit settings.php manually or use the Drupal installer to make it-- it will notice that the database is populated and not overwrite tables.
9. Download sites/example.org/files from old server and upload to new.

Extra note: to prevent downtime, we use a spare domain or subdomain and symlink it to the directory of the site, example.org, that we are going to move over once it all works.
