Dynamic task list will not migrate content within unmigrated wiki markup macro

Running the Unmigrated wiki markup migration Task does not migrate Dynamic Task lists.

Repro steps:

1. Create a page with the following source:

   <ac:macro ac:name="unmigrated-inline-wiki-markup">
   <ac:parameter ac:name="atlassian-macro-output-type">BLOCK</ac:parameter>
   <ac:plain-text-body><![CDATA[{dynamictasklist:IT Setup}\\
   ||Completed||Priority||Locked||CreatedDate||CompletedDate||Assignee||Name||
   |F|H|F|2007-09-03|          | |Determine if new interface / edit existing required 		(IT)|
   |F|H|F|2007-09-03|          | |Create Jira Item		(IT)|
   |F|H|F|2007-09-03|          | |Source client account references from third party		(IT)|
   |F|H|F|2007-09-03|          | |Commit and release changes to code		(IT)|
   |F|H|F|2007-09-03|          | |Manual test trading		(IT)|
   |F|H|F|2007-09-03|          | |Automate changes / Add to DEPENDS		(IT)|\\
   {dynamictasklist}]]></ac:plain-text-body>
   </ac:macro>
   

2. Run the Unmigrated wiki markup migration Task.
3. Check the unchanged content of the page.

The migration task does not display any error in the logs.

Workaround:

1. Shutdown Confluence.
2. Run the following query in your databse:
   Please note this will modify your database, please make sure you take a backup before applying the changes in case you need to roll back,

   update BODYCONTENT set body = replace(body, '<ac:macro ac:name="unmigrated-inline-wiki-markup"><ac:parameter ac:name="atlassian-macro-output-type">BLOCK</ac:parameter><ac:plain-text-body><![CDATA[{dynamictasklist', '<ac:macro ac:name="tasklist"><ac:plain-text-body><![CDATA[{dynamictasklist')
   where contentid in (select contentid from content where prevver is NULL AND contenttype IN ('PAGE','BLOGSPOT') AND content_status='current');

   This query may need a bit of fine tuning to adapt to the way your content is stored

3. Start Confluence.
