[Vineet Kumar]

Hi, We are plannning to upgrade the Jira from 4.0 to 7x, So, the plan is to pass the bacup file through all the intermidate major version of Jira and finally import it to Jira 7. We were sucessfully imported the data from Jira 4.0 to Jira 4.4.5 but while importing the backup of Jira 4.4.5 to jira 52. we received the below error which has blocked us. Can someone help, Thanks in Advance.

Error parsing export file. Your export file is invalid. This may be due to a CDATA bug in older versions of JIRA (http://jira.atlassian.com/browse/JRA-4980). Exception is org.xml.sax.SAXParseException; Attribute name "ent" associated with an element type "UserHistoryItem" must be followed by the '=" character.

Did you try the xml fix documented in that bug?

@Nic, Yes i tried it after reading your response, But i am getting the same error.

@Nic, The error was not detected by the xml fix but after going through the xml backup manually we found a special character which came into the entity id.
