Upgrading EPrints 3 versions
EPrints developer Christopher Gutteridge gives the following instructions:
Upgrading 3.0.0 to 3.0.1 is very easy - just run configure with the --prefix set to the location of the current repo (you may also need to set the --with-user and --with-group options). Then run install.pl to upgrade the software. Then run
epadmin upgrade REPOID
for each repository to update the database. Normally minor updates would not update the db at all. In this case all it does is add an SQL index to make things go faster.
