Task Completed:

Congratulations…..!!!! Your Open Journal System has been upgraded to version OJS 3.3.0-13. You can check by refollowing step 2.4

Note: Above mentioned steps do not promise a successful upgrade. You might face trouble upgrading if you have installed a customized theme and plugin. These steps are derived from the actual documentation of the Open Journal System. You are requested to higher expert for this task. In case of any destruction to your database, I am not liable for that.

Precaution Steps for Open Journal System upgrade:

(a) Find the perfect time to upgrade

In a software world, the upgrade is an ongoing process. As a result, PKP continuously releases new minor versions of OJS. It is not advisable that each time you need to keep on updating the OJS each day because it is a time-consuming and complex task. So to solve this confusion, one should keep track of new features available in new releases. Analyze your requirements against the newly released features; if those are necessary, please go for them. However, security point of view, you should upgrade at least once a year. 

(b) Check plugins & important features Compatibility

At the time of the upgrade, ensure that any plugin important to your user is compatible with the OJS 3. If not, you need to wait until the new bug-free version of OJS has been released. Because some of the immediate new version releases may not support all plugins, this care is not only limited to the plugins but must also be kept in mind for other essential features. So it is better to chat with editorial teams before going for an upgrade.

(c) Which version to go for? (i.e. OJS 3.1.0, OJS 3.2.0, or OJS 3.1.0-1; OJS 3.2.0-1)

Generally, it is good to go for the latest version. On the contrary, you must know the type of the latest version. Is it a major or minor update release? Because if you go for the immediate major release, it might contain some bugs, which will be addressed during the subsequent minor release. So my advice is to always go for the latest minor release.

(d) Making Aware the editorial team and other concerns

As this upgrade procedure will affect many areas, relevant entities must be aware of this for a seamless user experience. Before the upgrade announces, all involved parties, like an editorial team, editors, and section editors, must be aware of the upgrade procedure. Though the reviewer and author will not face significant issues with the upgrade.

(e) Make necessary changes to the server to meet the requirements of OJS 3.

You need to focus on the below-mentioned requirements. These have been generated by PKP from users’ feedback, so you may need some extras apart from the below-mentioned.

  • PHP >= 7.2
  • MySQL >= 4.1 
  • PostgreSQL >= 9.1.5
  • Apache >= 1.3.2x or >= 2.0.4x 
  • Microsoft IIS 6
  • Operating system: Any OS that supports the above software, including Linux, BSD, Solaris, Mac OS X, Windows

(f) Prepare a list of items automatically moving to the new version or requiring manual efforts. 

  • Submissions
  • Users
  • Roles/Permission setting
  • Announcements
  • Sections
  • The following items will need manual efforts for moving to OJS 3:
  • Journal Information – Masthead, Editorial Team, Permissions, etc.
  • Customizations – CSS, images, color codes
  • Journal setup settings and textual information
  • Plugins
  • Pages/ Menus
  • Links
  • Files
  • Customized email templates
  • Reviewer Forms
  • Custom blocks
  • PDF uploads

(g) Deletion of the existing database.

This step will wipe out all spam users. So take this as an opportunity to clean up unwanted users from the database. You can manually identify the spam users present in your system by SQL query. This query utilizes email domains fetched during the new user registration.

(h) Perform sandbox testing.

A sandbox is an isolated testing environment that enables users to run programs or open files without affecting the application, system, or platform on which they run. The upgrade task is very intensive, so it is better to be double-sure before going to the war zone.

(i) Evaluate, test, and troubleshoot your sandbox OJS 3 site

This is the right time to test the website involving all stakeholders (Journal Managers, Editors, and Section Editors) in a secure environment. Collect the feedback from the users and, if necessary, go back to the drawing board for changes. This is where you can test the workflow and train the stakeholders.

(j) Adjust your theme (If the custom theme is applied)

After the upgrade, it is most important to check the applied theme. Because the older version theme might not work correctly in the new OJS 3, I suggest checking for the OJS 3 themes to overcome this option.

Why do you need to upgrade OJS 2 to OJS 3?

Since the inception of OJS, PKP has released two major versions that are OJS 2.x and OJS 3.x. Currently, both versions are doing extremely well in terms of managing scholarly research work publications throughout the world.

As you know, current circumstances demand constant upgrades and novelty in each thing. So that OJS is not the exception over here. The developer of OJS, known as the Public Knowledge Project (PKP) keeps on pushing the boundaries of OJS to meet the user’s demands. 

In continuation, I would say PKP is pouring the new features and functionalities in OJS in form of frequent upgrades. As a result in recent times (the year 2022), the new version, OJS 3.x has been released with great features and enhanced security functions. So, to take the advantage of the new add-ons everyone must need to upgrade from the older version to the latest.

Upgrade OJS 3.X to OJS 3.3.0-13 >>

You might ask a question:

If OJS 2 is working perfectly fine, then why should I move on to OJS 3? Your question is not at the wrong place, as a counterargument, I would like to add that, OJS 2 is lacking in many areas such as look and feel, security, and functionality. 

Time Change

If you do not migrate to the latest version, you will not be able to enjoy the extra benefits from the latest offerings of OJS 3. For better clarity please refer subsequent section that describes the additional features and benefits provided by OJS 3.

What are the features provided by OJS version 3 and 3.2.x compared to OJS 2.x?

  • Existing OJS users are more comfortable with OJS 3.
  • OJS management feature
  • Flexible editorial workflow
  • Author Plugins also recommend this upgrade.
  • Support a “draft” option for reviews.
  • Easy compatibility with third-party plugins.
  • New default themes
  • Statistics reports
  • More responsive in terms of page loading speed and mobile-friendly.
  • Author records can be deleted very easily by submission deletion.
  • Multilingual author name support
  • Support for thematic collections or categories of articles
  • Submissions from removed journals can be counted.

Important: Things to consider before upgrading OJS 2 to OJS 3 :

  • The OJS 2 Theme or the design template you used before, may no longer support the latest OJS version
  • Some plugins no longer support OJS 3, including Books for Review and Dataverse Please note that for you to take an inventory of your useful and frequently used plugins and features, you should check and trace details regarding their availability for newer OJS versions before you decide to upgrade.
  • Some data is not included as a result of the OJS upgrade. We have listed the exclusion of data that be found.
  • The pop-up that shows the detail of each editorial team won’t be supported. The solution for this issue is to create a custom static page or custom design for each of the Editorial members including their affiliation.


To summarize, I would say that an OJS upgrade is a very necessary thing to do if you want your hosted journal more secure, efficient, responsive, and reliable. However, this process is not an easy task for a normal human being. It requires expert knowledge. So, I would suggest you to higher an expert agency for the said purpose.
