Upgrading from S4-alpha12

[titantoppler at gmail.com]

Hi list,

I'm attempting to upgrade from my (very old) installation of S4 alpha 12,
to the current build of S4.

After pulling down the latest source and compiling+installing, I'm doing
the 'upgradeprovision --full' step to upgrade the database.

However, I'm running out of space. Upon further investigation, I realised
that this step seemed to be copying the 'sysvol' folder to a
/usr/local/samba/private/backupprovision(some-random-letters). Since my
users' data files are really huge, doing so fills out my hard disk really
quickly.

Why is this happening (meaning the need to copy the files) - I had thought
the provisioning step would be upgrading the database only, without
touching my files? Is there a way around that?

Thanks!
