I have recently inherited several omeka sites.
They range in version: 1.5, 2.1.4, 2.4, 2.5.
After some trial & error in attempting to upgrade from 1.5 to 2.5,
I have discovered an upgrade path with respect to the database:
1.5 --> 2.0 --> 2.4.1 --> 2.5
Are raw MySQL scripts available to perform the database upgrades, rather than using the dashboard?
Upgrading these sites would go much faster if I could run database upgrade scripts successively,
and then simply install the newest version of the software.
