Server (with Backbone) to Server → Cloud to Server (with Backbone)

This article guides you through the steps to take for the migration of a Server (where Backbone is configured) to server synchronization to a Cloud to Server (where Backbone is configured) synchronization.

Prerequisites

• You are synchronizing to a Server instance which also has Backbone installed

• You have configured/set up the synchronization on your instance

• Only you are migrating your Server instance to Cloud

• There are no errors in the troubleshooting tab of the configuration. If there are, please solve these first

• You need to have Python 3 installed on your computer

• You need an Atlassian Access Token for your Cloud instance: Manage API tokens for your Atlassian account | Atlassian Support

Things to Keep in Mind

• You can't set up the synchronization on the Cloud side which means that your partner will need to set up/configure the synchronization

Migration Steps

These steps assume the following setup:

• Project SA - project that should be migrated from Server to Cloud

• Project CA - project SA after it has been migrated from Server to Cloud

• Project SB - partner project on Server

Step-1: Export your synchronization data

1. Stop the original running synchronization

2. Export the synchronization config for this synchronization

3. Download the synced issue data for this synchronization (open the synchronization config and click ••• > Download synchronized issues)

Step-2: Migrate your server project to the Cloud

Migrate the project SA using the Jira Cloud Migration Assistant. We’ll call the new Cloud project in this guide CA.

Step-3: Modify exported data

1. Open the exported synchronization config file you created in step 1.2 (filename ends with “config_export.json”)

   1. Rename "firstConnector" (at the beginning of the file) to "secondConnector"

   2. Rename "secondConnector" (in the middle of the file) to "firstConnector"

2. Perform a Backbone Cloud Migration preparation with the files created in step 1.2 and step 1.3

3. Open output.json and rename:

   1. "firstConnector" (at the beginning of the file) to "secondConnector"

   2. "secondConnector" (in the middle of the file) to "firstConnector"

Step-4: Create a new synchronization

1. Go to Project SB and start a new sync with project CA

2. Import synchronization config that you exported and changed in step 3.1

3. Pair the issues (click ••• > Pair existing issues >  Pair existing issues synced with Backbone before)

   • Upload the file output.json of step 3.3

   • Make sure to keep “update sync info panel“ unchecked

4. In the synchronization config, check every tab ('Issue types', 'Fields - mappings' etc.) for validation errors – these will appear in yellow warning boxes. These warnings can appear due to custom IDs (issue type IDs, field IDs, etc) being different in the new Jira instance. Find any errors and correct them.

   1. Note: if you are using a user field mapping, make sure to set it to "User Passthrough Mapping (by email)"

Step-5: Start the synchronization

1. Start the new synchronization

2. In the new synchronization, trigger a resync in both directions (with only the summary field, so the resync doesn't take long). This is done in order to recreate the information in the sync info panel.

3. Once you have verified everything is working correctly, delete the original synchronization. This will also delete the old information in the sync info panel.
