Slide locks lost with upgrade to Jahia 4.1

Hi!

I am trying to upgrade from jahia version 4.0.7_01 to 4.1.1_01 using the
official patch. I have to migrate 8 Go of files for our production server,
so that I try to be carefull as much as possible.

The patch has been applied successfully after some modifications of the
original Slide 1 tables structure into our jahia database (running on MySQL
4.0.27). In fact, there were some integrity problems that I have corrected.

Full of motivation, I try the new Jahia 4.1, but when I use the Jahia
filemanager, I see that all locks on webdav files that are published on
pages are gone, so that I (and all other users) can delete all files without
any protection! I test the case of uploading some new files and the latter
are locked after I have published them on a page.

So my question is how to restore the lost locks or how to create them again
with the new slide 2 ? 

It seems that the offical Jahia 4.1 patch simply drops the jahia_slide_lock
table from the previous Slide 1.


Waiting for some help...
