upgrading error 5.2.0j to current version

[golightly]

hi all,
if I use the "Upgrade Wizzard" I get:
Fatal error: Call to undefined function posix_getpwuid() in ... (path of my sugarserver)
any ideas how I can do an update without the "Wizzard"?
We already have quite an amount of data in the mysql dataspace - so we would need to migrate those informations to the most current version.
thanks for your help!
