I took the steps from:
https://confluence.atlassian.com/jirakb/migrating-from-jira-server-to-jira-cloud-779160826.html
The third step is rather vague:
Create an XML backup of the issue data and compress the attachments.
Since the zip does contain the XML files.
And then I get this error:
Import error
There was an error importing file 2016-Dec-20--1245.zip: "There was an error parsing the entities.xml file: An invalid XML character (Unicode: 0xb) was found in the CDATA section.". Please try again or choose a different file.
How can I correct this? I want to migrate from JIRA Server to JIRA cloud.
