sm_migrate.pl migration script returns "low disk space" error

Hi,

I'm trying to migrate SAM 7.2 Windows 2003 to a new host SAM 9.1 Windows 2008 R2. I managed to run the migration script (sm_migrate) on the old server and produce a backup.zip file.

After moving the backup.zip file to the new SAM 9.1 host, I ran the sm_migrate.pl script to restore the custom config files and it return with "low disk space" error. I have 1.61TB free space on the specified drive.

D:\InCharge\SAM\smarts\bin>sm_perl sm_migrate.pl --archive=D:\InCharge\SAM\smarts\backup.zip --new=D:\InCharge\SAM\smarts

Anyone has any suggestion?

Thanks
