Migration Errors

[moschap]

I am trying to migrate a sugar OS installation from a linux AMD box(128MB, 20GBHDD etc ) to a faster Linux box(80GB,512MB), i have moved the database backup and the sugarcrm folder from the old box to the new, and everything is working well except my astericks upgrade/patch. When i go the Ugrade wizard of the new box i see this error : PCLZIP_ERR_MISSING_FILE (-4) : Missing archive file '/var/www/html/RCCGRM123/cache/upload/upgrades/patch/sugarOS-asteriskOS_450_1.3.3.zip' but the thing is that the zip folder really exists in the directory listed above. Please can someone help me with this problem, on why sugarcrm does not see the folder.

php is 5.1.2
apache -- 2.2.0
fedora core 5
mysql -- 5.0.18
sugarcrm OS 4.5.0RC(build 1050)

Are you able to install [successfully] ANY other patches, upgrades, or modules to this particular SugarCRM deployment?
If you don't know, then try..

The reason I ask is in order to try and pinpoint the problem [area], as I would make suggestions like [php] compression libraries, or maybe _SERVER array variables such as paths (PHP configuration), etc. which could be different between the different servers.. And again another possibility might be that this server setup of yours lacks the appropriate/neccessary compression libraries..

Anyways, my first suggestion is to try and determine IF that Sugar installation can uncompress ANY other zip file [being modules/upgrades/patches/etc].
Obviously, the awnser to that question will determine whether or not the problem is specifically caused by either THAT zip file and/or SugarCRM....ONLY, and nothing related to the environment (i.e. web server, PHP, php configuration, permissions, etc.)

And now that I just mentioned permissions, that is ANOTHER possibility, but can be essentially excluded or eliminated by coming up with an awnser to my first question..
