Hints about network administration and other matters…

From the codex:

• Before You Create a Network
• Create A Network
• Multisite Network Administration
• Migrating Blogs to Multisite
  • You will probably have to run repl.php again after migration to fix links in blog content.
  • Beware the change of the ‘uploads’ directory to ‘uploads/site/#’ which might take more replacing. You also may need a symbolic link between the domain name and the actual uploads directory for the site in the multisite uploads directory. Take a look there for examples.
  • Don’t forget to enable and set up appropriate plugins, like Twitter Digest.
• Moving WordPress Multisite
