Hi We are trying to migrate XWiki 1.3 to 3.1. Getting the following error message: Near the start of the stack trace: <paste begin> com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3201 in 3: Exception while saving document xwiki:XWiki.XWikiRights Wrapped Exception: Failed to commit or rollback transaction. Root cause [] com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:424) com.xpn.xwiki.XWiki.getXWiki(XWiki.java:493) <paste end> And getting the following at the end of the same stack trace: <paste begin> Caused by: java.sql.BatchUpdateException: Column 'XWP_NAME' cannot be null at com.mysql.jdbc.PreparedStatement.executeBatchSerially(PreparedStatement.java:1666) at com.mysql.jdbc.PreparedStatement.executeBatch(PreparedStatement.java:1082) <paste end> Is there some way of identifying what the core issue is? Can this be corrected, or are we stuck not being able to migrate our XWiki?
