When JCMA is used to migrate Jira Server (users/groups, data, attachments) to the cloud, using different plans, JCMA keeps track of what fields were migrated and when. This helps admins to understand which fields were already migrated and helps to avoid duplicates.

There's an ongoing Feature Request aiming to empower administrators to remove the "migrated" text from the migrated custom fields:

• MIG 186 - Give users the option to remove the migrated text from fields.

It’s highly recommended that those going through this knowledge base vote and subscribe to the feature in order to receive updates once they are posted to the ticket.
While the feature’s not implemented, this knowledge base aims to explain how to circumvent this behavior.

How to manually remove the "Migrated on" note on custom fields:

1. Please access the direct link for the custom fields configurations for Jira Cloud on https://yourcloudsite.atlassian.net/secure/admin/ViewCustomFields.jspa
2. There, you can check any custom fields that have the "Migrated on" note and click on the  three dots > Edit details :
   
   
3. On the  Description , you can edit as you like and click on  Update .
   
4. Done!

How to manually remove the "Migrated on" note on standard fields:

1. Please note that this needs to be done on every different project that you would like to edit the "Migrated on" note. This can be easily be based on this URL:  https://yourcloudsite.atlassian.net/plugins/servlet/project-config/projectkeyhere/fields
    Please change the "yourcloudsite" and the "projectkeyhere" values on the URL above.
2. It's known that each project can have different field configurations for different issue types, however, steps will not differ much as we going to select the  pen icon  to  edit .
   
3. There you have to select the desired field and click on  Edit.
   
4. Now here is where the expected modification will take place, change the  Description  as you like and click  Update.
   
5. Done!

Please note that when updating the description field, you need to provide some string in the Description field, if you leave the Description field with blank value and update it, then, the string (Migrated on…) will appear again. This basically inherits the description value of the custom field when field is left with blank value.
