Editing Upgrading between EPrints 3.3 Versions (section)

=== From a Linux Package Manager ===
If you have installed from the Deb or RPM package, then you can just upgrade this.  However, it is recommended that you have done a backup before doing this.  Also if this is on a production server, that you do this during an extended period of scheduled downtime and have previously tested the upgrade on a pre-production server.

Once the package upgrade has completed make sure to run both ''epadmin upgrade'' and ''epadmin update'' on all archives.  The package manager may only tell you need to run ''epadmin upgrade'' but ''epadmin update'' is also needed to ensure newly added fields to data objects are also incorporated.
