# Migration with unsupported Jira versions causes errors

 App migration is not possible due to an unsupported app version:

## Explanation

Migration from on-prem to cloud instances is usually supported on the latest version of our application.

If you are using a Jira version that is unsupported by the latest on-prem version of our app, migration will not be possible and you will see a version on the below error message (app version may vary):

The reason for this behaviour is that we are trying to minimize possible errors stemming from bugs during the migration process.&#x20;

As we fix them along the way, we are introducing new versions of our applications and supporting newer Jira versions.

## Solution

The easiest way to get around this issue is to check supported Jira versions of our application on Atlassian Marketplace and update your Jira.

If that is not possible, reach out to us with your current on-prem Jira and Email This Issue versions and we will do our best to help with the migration.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.meta-inf.hu/email-this-issue/server-to-cloud-migration/server-to-cloud-automatic-migration-tool/migration-with-unsupported-jira-versions-causes-errors.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
