If your database structure/data is upgraded, the migration process will now trigger a reindex of all your content after deployment to Tomcat. Some repository content will be not be discoverable until this reindex process is complete. For large repository instances, this process could take some time to complete. Optionally, you may choose to skip this automatic reindex and run a manual reindex at a later time. For more information on doing so, see the note under the optional "Upgrade your Database" step below. |
Note | ||
---|---|---|
| ||
With the addition of our automated database upgrades, we highly recommend AGAINST customizing the DSpace database tables/structure or backporting any features that change the DSpace tables/structure. Doing so will often cause the automated database upgrade process to fail (and therefore will complicate your next upgrade). If you must add features requiring new database tables/structure, we recommend creating new tables (instead of modifying existing ones), as that is usually much less disruptive to our automated database upgrade. |

build.properties
configuration file has been replaced by an enhanced local.cfg
configuration file. The new local.cfg
allows you to easily override any configuration (from dspace.cfg
or modules/*.cfg
files) by simply copying it into your local.cfg
and specifying a new value. It also provides enhanced configuration options as detailed in the Configuration Reference documentation. The old build.properties
file is no longer used nor supported.modules/*.cfg
files) had to be renamed or prepended with the name of the module. This means that 5.x (or below) configurations are no longer guaranteed to be compatible with 6.x. If possible, we recommend starting with fresh configs (see below), and moving all your locally customized settings into the new local.cfg
file.disseminate-citation.cfg
to citation-page.cfg
). See this features documentation for more details.The DSpace Lightweight Networking Interface (LNI), supporting WebDAV / SOAP / RPC API, has been removed from DSpace 6.0 or above. We recommend using REST or SWORD (v1 or v2) as a replacement. However, if you still require it, the old (unmaintained) LNI codebase is still available at https://github.com/DSpace/dspace-lni

[dspace]/config
For highly customized DSpace instances, note that the format of the following configuration files has changed. If you have customized these configuration files, carefully re-integrate your custom settings.
dspace/config/dspace.cfg
dspace/config/spring/api/discovery.xml
dspace/modules/xmlui/src/main/webapp/sitemap.xmap
Note the presence of new class names in this file. In particular,note the removal of StandardOpenSearchGenerator
Replace your old build.properties file with a local.cfg (REQUIRED if upgrading from DSpace 5 or previous): As of DSpace 6.0, the build.properties
configuration file has been replaced by an enhanced local.cfg
configuration file. Therefore, any old build.properties
file (or similar [dspace-source]/*.properties
files) WILL BE IGNORED. Instead, you should create a new local.cfg
file, based on the provided [dspace-source]/dspace/config/local.cfg.EXAMPLE
and use it to specify all of your locally customized DSpace configurations. This new local.cfg
can be used to override ANY setting in any other configuration file (dspace.cfg
or modules/*.cfg
). To override a default setting, simply copy the configuration into your local.cfg
and change its value(s). For much more information on the features of local.cfg, see the Configuration Reference documentation and the local.cfg Configuration File section on that page.

cd [dspace-source] cp dspace/config/local.cfg.EXAMPLE local.cfg # Then edit the local.cfg, specifying (at a minimum) your basic DSpace configuration settings. # Optionally, you may copy any settings from other *.cfg configuration files into your local.cfg to override them. # After building DSpace, this local.cfg will be copied to [dspace]/config/local.cfg, where it will also be used at runtime. |
Build DSpace. Run the following commands to compile DSpace :
Code Block |

cd [dspace-source]/dspace/ mvn -U clean package |
The above command will re-compile the DSpace source code and build its "installer". You will find the result in [dspace-source]/dspace/target/dspace-installer

Mirage 2 is a responsive theme for the XML User Interface, added as a new feature in DSpace 5. It has not yet replaced the Mirage 1 theme as the XMLUI default theme. To enable Mirage 2, add the following to the <theme name="Mirage 2" regex=".*" path="Mirage2/" /> It is important to do this before executing the maven build. Mirage 2 is not yet activated in the default "mvn package" build. To include it as part of the build, run: mvn -U clean package -Dmirage2.on=true The speed of this specific step of the build can be increased by installing local copies of the specific dependencies required for building Mirage 2. The Mirage 2 developer documentation provides detailed instructions for these installations. After the installation of these dependencies, you can choose to run: mvn -U clean package -Dmirage2.on=true -Dmirage2.deps.included=false Warning: The Mirage 2 build process should NOT be run as "root". It must be run as a non-root user. For more information see: Mirage 2 Common Build Issues |

script. (Many Unix-based installations will have a startup/shutdown script in the /etc/init.d
or /etc/rc.d
directories.)Update DSpace Installation. Update the DSpace installation directory with the new code and libraries. Issue the following commands:
Code Block |

cd [dspace-source]/dspace/target/dspace-installer ant update |
The above command will also automatically upgrade all your existing Solr indexes (e.g. for Discovery, Statistics, OAI-PMH) to the latest version. For large instances, this may take some time. But, it is important to ensure that your indexes are usable by the latest version of DSpace.
dspace.cfg
(or any of the modules/*.cfg
), it's recommended to simply override the default values in your own local.cfg
. That way, your local.cfg
can serve as the record of which configurations you have actually tweaked in your DSpace, which may help to simplify future upgrades.modules/*.cfg
files had their configurations renamed to be pre-pended with the module name. As a basic example, all the configuration settings within the modules/oai.cfg
configuration now start with "oai.
". Unfortunately, these means that DSpace 5.x configuration files are NOT guaranteed to be compatible with DSpace 6. For more information on configurations in DSpace 6 see our updated Configuration Reference.config
directory, and its subdirectories. It is helpful to compare your current configs against a clean checkout of your current version to see what you have customized. You might then also want to compare your current configs with the configs of the version you are upgrading to. A tool that compares files in directories such as Meld or DiffMerge is useful for this purpose.local.cfg
file, as described above. Examples of how this might be accomplished are provided in the Configuration Reference.[DSpacedspace]/config/GeoLiteCity.dat
file is no longer maintained by its provider. You can delete it. The new file is named GeoLite2-City.mmdb
by default. The upgrade process will automatically download a copy of the new database if you don't already have it. If you have configured a different name and/or location for this file, you should check the setting of usage-statistics.dbfile
in [dspace]/config/modules/usage-statistics.cfg
(and perhaps move your custom setting to local.cfg
).Decide which DSpace Web Applications you want to install. DSpace comes with a variety of web applications (in [dspace]/webapps
), each of which provides a different "interface" to your DSpace. Which ones you install is up to you, but there are a few that we highly recommend (see below):
"xmlui" = This is the XML-based User Interface, based on Apache Cocoon. It comes with a variety of out-of-the-box themes, including Mirage 1 (the default) and Mirage 2 (based on Bootstrap).Between the "xmlui" and "jspui", you likely only need to choose one.
"jspui" = This is the JSPUI-based User Interface, which is based on Bootstrap. Between the "xmlui" and "jspui", you likely only need to choose one.
"solr" (required) = This is Apache Solr web application, which is used by the "xmlui" and "jspui" (for search & browse functionality), as well as the OAI-PMH interface. It must be installed in support of either UI.
Deploy DSpace Web Applications. If necessary, copy the web applications from your [dspace]/webapps
directory to the subdirectory of your servlet container (e.g. Tomcat):
Code Block |
---|
cp -R [dspace]/webapps/* [tomcat]/webapps/ |
See the installation guide for full details.
First, you can optionally verify whether DSpace correctly detects the version of your DSpace database. It is very important that the DSpace version is detected correctly before you attempt the migration:
Code Block |
---|
[dspace]/bin/dspace database info # Look for a line at the bottom that says something like: # "Your database looks to be compatible with DSpace version ___" |
In some rare scenarios, if your database's "sequences" are outdated, inconsistent or incorrect, a database migration error may occur (in your DSpace logs). While this is seemingly a rare occurance, you may choose to run the "update-sequences.sql" script PRIOR to upgrading your database. If your database sequences are inconsistent or incorrect, this "update-sequences.sql" script will auto-correct them (otherwise, it will do nothing). Be aware, if you choose to run this script, please run the "update-sequences.sql" file that corresponds to your current version of DSpace (i.e. the version you are upgrading from), as this script occasionally changes between relesasesreleases. In the future, we hope to automate this step to avoid any sequence problems:
Code Block |
---|
# General PostgreSQL example psql -U [database-user] -f As of 6.4, this script can instead be run via [dspace]/etcbin/postgres/dspace update-sequences.sql [database-name] # ExampleFor for6.3 a PostgreSQL database and below, you have to run this via database tools # General PostgreSQL example psql -U [database-user] -f [dspace]/etc/postgres/update-sequences.sql [database-name] # Example for a PostgreSQL database named "dspace", and a user account named "dspace" # psql -U dspace -f [dspace]/etc/postgres/update-sequences.sql dspace |
Then, you can upgrade your DSpace database to the latest version of DSpace. (NOTE: check the DSpace log, [dspace]/log/dspace.log.[date]
, for any output from this command)
Code Block |
---|
[dspace]/bin/dspace database migrate |
The database migration should also automatically trigger your metadata/file registries to be updated (based on the config files in [dspace]/config/registries/). However, if this update was NOT triggered, you can also manually run these registry updates (they will not harm existing registry contents) as follows:
Code Block |
---|
[dspace]/bin/dspace registry-loader -metadata [dspace]/config/registries/dcterms-types.xml [dspace]/bin/dspace registry-loader -metadata [dspace]/config/registries/dublin-core-types.xml [dspace]/bin/dspace registry-loader -metadata [dspace]/config/registries/eperson-types.xml [dspace]/bin/dspace registry-loader -metadata [dspace]/config/registries/local-types.xml [dspace]/bin/dspace registry-loader -metadata [dspace]/config/registries/sword-metadata.xml [dspace]/bin/dspace registry-loader -metadata [dspace]/config/registries/workflow-types.xml |

If any database migrations are run (even during minor release upgrades), then by default DSpace will automatically reindex all content in your site. This process is run automatically in order to ensure that any database-level changes are also immediately updated within the search/browse interfaces. See the notes below under "Restart Tomcat (servlet container)" for more information. However, you may choose to skip automatic reindexing. Some sites choose to run the reindex process manually in order to better control when/how it runs. Skipping automatic reindexing involves two main steps, both of which must be executed prior to restarting Tomcat (or your servlet container): 1) First, you must manually update your database by running 2) If any database migrations are run, a empty "reindex.flag" file will be created at As you have disabled automatic reindexing, make sure to manually reindex your site by running WARNING: It is not recommended to skip automatic reindexing, unless you will manually reindex at a later time, or have verified that a reindex is not necessary. Forgetting to reindex your site after an upgrade may result in unexpected errors or instabilties. |
Sites with Oracle database backends (and Configurable Workflow enabled) may need to run a "repair" on your database.
In version 6.3, we fixed an Oracle migration issue related to Configurable (XML) Workflow. See DS-3788.
If you are upgrading an Oracle-based site to 6.3 from 6.0, 6.1 or 6.2 AND had Configurable Workflow already enabled, then you will need to manually "repair" your database to align it with the latest schema. This does not affect PostgreSQL-based backends or any sites that are upgrading from 5.x or below.
Simply run the following to repair your Oracle database: [dspace]/bin/dspace database repair
Restart Tomcat (servlet container). Now restart your servlet container Restart Tomcat (servlet container). Now restart your servlet container (Tomcat/Jetty/Resin) and test out the upgrade.

) for information on its status.Reindexing of all content for search/browse: If your database was just upgraded (either manually or automatically), all the content in your DSpace will be automatically re-indexed for searching/browsing. As the process can take some time (minutes to hours, depending on the size of your repository), it is performed in the background; meanwhile, DSpace can be used as the index is gradually filled. But, keep in mind that not all content will be visible until the indexing process is completed. Again, check the DSpace log ( [dspace]/log/dspace.log.[date]
) for information on its status.
Check your cron / Task Scheduler jobs. In recent versions of DSpace, some of the scripts names have changed.
Check the Scheduled Tasks via Cron documentation for details. Especially pay attention to the Solr Index optimization commands, which ideally should be run regularly (as noted in the previous step).
