In certain scenarios users might be required to downgrade Issue Matrix to lower version due conflicts with other plugins. For reference and such scenario see this [article](https://appfire.atlassian.net/wiki/spaces/SUPPORT/pages/2420670637/Issue+Matrix+5.x+causes+Script+Runner+8.53.0+crashes?atlOrigin=eyJpIjoiNzI4OGQ0YTVlZTM0NDIyYWE0OGQ3YTZlNDllNzE5YWEiLCJwIjoiYyJ9).

If you need to downgrade Issue Matrix from 5.x to 4.x version the following steps must be followed:

1. Uninstall 5.x version of the app.
2. Identify all Issue Matrix configurations on the current instance executing:

```
SELECT * FROM PROPERTYTEXT 
  INNER JOIN PROPERTYENTRY ON PROPERTYTEXT.ID=PROPERTYENTRY.ID 
  WHERE ENTITY_NAME='com.botronsoft.jira.issuelist.customfield.configuration.Configuration';
```

3. <u>***For each matrix there should be set of entries such as:***</u>

| ID | PROPERTYVALUE | ID | ENTITY_NAME | ENTITY_ID | PROPERTY_KEY | PROPERTYTYPE |
| --- | --- | --- | --- | --- | --- | --- |
| 11322 | <?xml version="1.1" encoding="UTF-8"?> <configuration:Configuration xmi:version="2.0" xmlns:xmi="[http://www.omg.org/XMI](http://www.omg.org/XMI)" xmlns:configuration="[http://www.botronsoft.com/issuematrix/model/1.8](http://www.botronsoft.com/issuematrix/model/1.8)" type="issue-links" jql="" filterJql=""><panelConfiguration hideSubTasks="true" hideIssueLinks="true" hideIssuesInEpic="true" showTableHeader="true" showIssueLinkDescription="true" defaultPageSize="7" showEmptyPanel="true"/><columns id="issuekey" inlineEditable="true"/><columns id="description" inlineEditable="true"/><columns id="priority" inlineEditable="true"/><columns id="status" inlineEditable="true"/></configuration:Configuration> | 11322 | com.botronsoft.jira.issuelist.customfield.configuration.Configuration | 10110 | config | 6 |
| 11323 | 1.8 | 11323 | com.botronsoft.jira.issuelist.customfield.configuration.Configuration | 10110 | emfVersion | 6 |

4. In order for the Matrix to work with lower app version the necessary updates must be done for each entry.
  1. Each “emfVersion“ entry must be updated to:
  2. Each “config“ entry must be updated changing model version to **1.7** and if there’s “**defaultPageSize**“ property in the configuration it must be changed to “**visibleLinks**“. So the entry from the example above should become:
5. Restart Jira
6. Install lower Issue Matrix version, e.g. 4.0.7, [https://marketplace.atlassian.com/apps/1212709/issue-matrix-for-jira/version-history?versionHistoryHosting=dataCenter](https://marketplace.atlassian.com/apps/1212709/issue-matrix-for-jira/version-history?versionHistoryHosting=dataCenter)
7. All Matrices should work now with lower app version.
8. Upon Issue Matrix app update to version 5.x all necessary updates to configuration entries will be handled automatically.

> ⚠️ Since this approach requires manual DB manipulations, it is highly recommended taking DB back up prior and testing on DEV instance all configuration updates prior executing them on any PROD instance.
