[Mediawiki-l] Dumping and restoring database

[Chuck Bishop]

Thanks Brion.  I was trying to restore over an existing database and
your suggestion seemed to work fine.

Is there any potential problems importing a backup database over an
existing one?

Thanks,
Chuck

Were you restoring into a blank, newly created database or one that 
already had a wiki in it?

If the latter, you need to either manually remove the old tables or 
make your dump with the --add-drop-tables or --opt options to 
mysqldump.

Uploaded images and any config or customized code files that you want 
to keep.
