Moving an existing installation of Omeka from one server to another
Before moving an existing Omeka project from one server to another, you should upgrade your existing installation to the latest version.
To move an existing Omeka project, you need to move a) the information in the database, and b) the files. The basic procedure for transferring both is this:
1) Install a blank version of Omeka on the new server as described at http://omeka.org/codex/Installation.
2) Export your existing database as a .sql file. There are pretty good instructions on how to do this using either phpMyAdmin or the command line, with screenshots, at http://codex.wordpress.org/Backing_Up_Your_Database (Omeka is very similar to WordPress).
3) Import your old database into the new database on the new server, also using phpMyAdmin or the command line.
4) Download files and folders from the old server to the hard drive of your computer. The files and folders you will need are these:
- archive/files
- archive/thumbnails
- archive/square_thumbnails
- archive/fullsize
- /plugins
- /themes
- any other files you have personally modified
5) Upload these files and folders to the new server, overwriting the existing ones.
6) Reactivate your plugins and your theme.
- You will have to change permissions, again, for the archive directory and its folders, and for any plugins that require directories to be writable. See Installation instructions
