Has anybody sucessfully exported Jira Data Connection and reimported it in MF Connect 23.4?

Hi Guys,

I'm running Connect 4.4.3 with some developer patches to synchronize Jira stories, bugs and epics to ALM. Works fine beside there is no defaut user feature.

That's why I parallel installed a MF Connect V23.4. I tried to export my Data Sources in V4.4.3 and import it in V23.4. No surprise - failed with an UnmarshallerImpl-Error.

I then created a new Jira-Datasource, exported it, deleted it and reimported it. Which also failes with an UnmarshalException.

Caused by: com.ctc.wstx.exc.WstxIOException: Invalid UTF-8 middle byte 0x6e (at char #45485, byte #43999)

Has anybody tried something similar with success?
