[xwiki-users] How to get data from XWiki 0.9.840 working on XWiki 1.0 Beta 1?

[jimmy at comkraft.com]

Hi, Fabian,

Thank you for sharing your tips. I am also trying to migrate from 0.9.840
to 1b3 using postgresql 8.1. I tried your approach and it did not work for
me. I think "upload_maxsize" is a custom property and I didn't have it in
my xwikilongs/xwikiproperties table.

I keep getting a lot of errors like this in my log files after my upgrade.
16:31:15,498 ERROR http-8080-Processor25
http://localhost:8080/xwiki/bin/view/Ma

Did you have this kind of CGLIB errors before?

Thanks
