Hello,
 
I'm trying to migrate from xwiki 1.0 to 1.1.milestone 1 engine using the export/import feature. I'm configured to use a MySQL database on both sides.
 
My exported .xar file is about 60Mo. I managed to go through following errors:
- limit of 10Mo from XWiki as attachment size
- limit of 1Mo as packet max size for MySQL
 
Now I'm getting the following error while trying to attach the Backup.xar file in my new wiki instance:
"java.sql.BatchUpdateException: Data truncation: Data truncated for column 'XWA_CONTENT' at row 1"
Any ideas ? The .xar file do not get correctly attached after this.
 
Best regards,
Jérémie
