Because I'm probably going to have to do some global search and replace on our entire Omeka collection, I'm wondering if this (unconventional) process will work for upgrading an Omeka 2.3 system to 2.4:
1. Install Omeka 2.4 to a new folder
2. Copy the custom themes, plugins and db.ini file over to the new folder
3. mysqldump the entire Omeka database, edit the resulting file and then restore
4. .... Success?
or am I missing something?
