You will require your database name, username and password, which can be found in:

archives/[archiveid/cfg/cfg.d/database.pl

The remainder of this page assumes your database name and repository are called 'myrepo' and your database username and password are 'myrepo'/'XYXY'.

Migrate the MySQL database

Dump the MySQL database for the repository:

$ mysqldump --user=myrepo --password=XYXY myrepo | gzip > myrepo.sql.gz

Transfer the MySQL dump file to your new server e.g.:

$ scp myrepo.sql.gz user@mynewserver:/tmp

Create the MySQL database on the new server and give it the appropriate permissions:

$ mysql --user=root --password
{ root password }
mysql> create database myrepo;
mysql> grant all privileges on myrepo.* to myrepo@localhost identified by 'XYXY';

Load the database:

$ gunzip -c /tmp/myrepo.sql.gz | mysql --user=myrepo --password=XYXY myrepo

Install EPrints on the new server

Install the version of EPrints that you want to migrate to (e.g. you may want to upgrade). Take a note of the EPrints user and group, as you may need to re-assign the ownership of the transferred repository files.

Migrate the Repository

Use tar and ssh to transfer your repository to the new server:

$ tar -czf - -C /opt/eprints3/archives myrepo/ | ssh user@mynewserver "tar -xzf - -C /opt/eprints3/archives"

Fix permissions and ownership:

$ sudo chown -R eprints:eprints /opt/eprints3/
$ sudo chmod -R 02775 /opt/eprints3/archives/

Migrate the Apache Configuration

If you have customised your Apache configuration you will need to transfer it:

$ scp /opt/eprints3/cfg/apache/myrepo.conf user@mynewserver:/opt/eprints3/cfg/apache/myrepo.conf
$ scp /opt/eprints3/cfg/apache_ssl/myrepo.conf user@mynewserver:/opt/eprints3/cfg/apache_ssl/myrepo.conf

Upgrading the repository

Skip if you installed the same EPrints version

$ ./bin/epadmin upgrade myrepo

Finishing

Make sure your repository is OK:

$ ./bin/epadmin test

For example you may need to install extra dependencies.

Generate any missing Apache configuration:

$ ./bin/generate_apacheconf

Restart Apache.
