This article explains the steps required when migrating a Jira Server or Data Center instance to Jira Cloud when you were using JMWE workflow extensions on your Jira Server instance.

title | Jira Cloud Migration Assistant support |

|
The new Atlassian App Migration Platform (currently under development) will enable all Atlassian Marketplace Partners apps to build automated migration paths for their apps. JMWE will take advantage of this platform to support migrating JMWE-enabled workflows from Jira Server/Data Center to Jira Cloud. You can track the progress of this project here. |
Background:
Because of the way Atlassian's Connect framework is implemented, workflow extensions (validators, conditions and post-functions) provided by add-ons are incompatible between JIRA Server and JIRA Cloud. The entire JMWE configuration is contained within the workflows themselves. So you need to take a backup of your entire JIRA Server instance, identify the workflows and transitions that use JMWE workflow extensions, and fix them.
Challenges
Workflows using JMWE post-functions/conditions/validators in the Server will break on the Cloud because post-function configurations are incompatible with their Cloud equivalents.

Step 1 - Publish all your workflowsBefore you begin fixing your workflows, publish all your workflows to avoid duplicate work (between the draft and corresponding published workflow) Step 2 - Backup the Server instanceUsing JIRA's XML backup utility backup your entire JIRA Server instance. Step 3 - Manually edit the XML- Extract the backup and open the
entities.xml file with any text editor (one that can open large files) - Edit the XML file to replace the Hide transition and Field is required validator with their equivalents
- Hide transition
- Search for
<arg name="class.name">com.innovalog.jmwe.plugins.conditions.NonInteractiveCondition</arg> - You should see XML for the condition similar to this
- Replace with
<arg name="class.name">com.atlassian.jira.workflow.condition.RemoteOnlyCondition</arg> throughout the file using ReplaceAll. - The replaced validator should look similar to this:Image Modified
- Field is required validator
- Search for
<arg name="class.name">com.innovalog.jmwe.plugins.validators.FieldRequiredValidator</arg> - You should see XML for the validator similar to thisImage Modified
- Edit the
<validator>...</validator> element:
- Remove the
<arg name="hidFieldsList"></arg > line, if it exists - Add this line:
<arg name="contextHandling">no</arg> - On the
<arg name="fieldKey">...</arg> line replace, fieldKey with hidFieldsList - On the same line, replace commas separating the fields with "@@"
- Add @@ after the last field
- Replace
<arg name="class.name">com.innovalog.jmwe.plugins.validators.FieldRequiredValidator</arg> with <arg name="class.name">com.atlassian.jira.workflow.validator.FieldRequiredValidator</arg> - The replaced validator should look similar to this:
- Find the next instance of the search.
- Repeat step iii until you reach the end of the file.
By now, you will have completed the XML fixes for workflow conditions, validators and unavailable workflow post-functions. The remaining fixes must be done by recreating/modifying the post-function and deleting the existing ones. Step 4 - Identify workflows and transitions using JMWE post-functions that need to be recreatedAt the end of this step, you will create a table with the workflow name and the transition names of all the workflows containing JMWE post-functions that need to be recreated - Unlink Issues post-function
Search for the text - <arg name="class.name">com.innovalog.jmwe.plugins.functions.UnlinkIssuesFunction</arg> Work your way up on the file from the line that contains <arg name="class.name">com.innovalog.jmwe.plugins.functions.UnlinkIssuesFunction</arg> to find the name of the transition on which the post-function is configured. You can identify it under the <actions> tag. Image ModifiedWrite down the transition name in the table. Transition Name | Workflow Name |

Step 5 - Identify workflows and transitions using JMWE post-functions that need reworkIn this step identify workflows and transitions using JMWE post-functions that need rework. At the end of this step you will have three tables with workflows, transitions and post-functions that have: - Groovy scripts in the Conditional execution section
- Groovy expressions or Groovy templates to set a field of an issue or comment an issue
- a specific user in the Run as section
Identify post-functions with Conditional execution script- Search for the text
<arg name="useGroovyCondition">yes</arg> - Work your way up and look at
<arg name="class.name"> to identify the name of the post-function (look at the end of the line). - Ignore and find the next instance of the search if it is either of the following:
<arg name="class.name">com.innovalog.jmwe.plugins.functions.CreateIssueFunction</arg> <arg name="class.name">com.innovalog.jmwe.plugins.functions.EmailIssueFunction</arg> <arg name="class.name">com.innovalog.jmwe.plugins.functions.LinkIssuesFunction</arg> <arg name="class.name">com.innovalog.jmwe.plugins.functions.UnlinkIssuesFunction</arg>

Step 6 - Import the backup into your JIRA Cloud instance- Re-zip the extracted files.
- In Windows: Select all the extracted files and re-zip them using any tool, say 7z or
- In Linux: Navigate to the directory where the files are that you want to zip. Then type:
zip newbackup file1 file2 file3 - In Mac: Navigate to the directory where the files are that you want to zip. Then type:
zip -r backup.zip newbackup.zip
- Log in to JIRA Cloud as an administrator.
- Import the backup into your JIRA Cloud instance using Jira Import Wizard in Import and Export section.
Step 7 - Install the JMWE add-onSee here to know how to install the JMWE add-on Step 8 - Fix your workflowsIn this step you will do the remaining fixes: - Recreating the workflow extension and deleting the existing ones or
- Edit the workflow extension and modify it.
Recreate the workflow extensions in Jira Cloud- Refer to the table prepared in Step 4
- For each affected workflow listed in the table, open the workflow in an edit mode in the Cloud and Server.
- For each affected transition listed of the workflow, go to that transition in the editor and then to the Post-functions tab.
- Locate the post-function in JIRA Cloud. You can easily identify JMWE post-functions imported from Server because they appear strange with the Class:
com.innovalog.jmwe.plugins.functions.UnlinkIssuesFunction similar to this: Image Modified - Identify the name of the post-function looking at the class name (look at the end of the line).
- Locate the same post-function in JIRA Server by its position in the list and edit it to see its full configuration.
- Recreate the post-function:
- Click on
Add post-function in JIRA Cloud. - Recreate the post-function looking at its equivalent configuration in JIRA Server.
- Move the post-function right before the existing post-function
- Delete the existing post-function in JIRA Cloud.
- Once all the transitions in a workflow are fixed, publish the workflow.
Modify the workflow extensions in Jira Cloud- Refer to the table prepared in Step 5
- For each affected workflow listed in the table, open the workflow in an edit mode in the Cloud and Server.
- For each affected transition listed for the workflow, go to that transition in the editor and then to the Post-functions tab.
- For each post-function listed in the table locate the Post-function in JIRA Cloud looking at the same post-function in JIRA Server by its position in the list.
- Edit the post-function. If the fix is for
- A Conditional execution/Groovy expression/Groovy template, look at the script in the Server and write a Nunjucks template that is equivalent to the existing one. Save the post-function.
- The Run as specific user, look at the selected user in the Server and select the same in the Cloud. Save the post-function.
- Once all the transitions in a workflow are fixed, publish the workflow.
