Stsadm Export/Import library in SharePoint 2007 limitation?

Hi, I want to move some document libraries from one site collection to another site collection and for moving I am using export and import stsadm command. One library size is around 90 GB and some others are around 60 GB, 50 GB, and 25 GB (including file versions).
I want to know is there any limitation for export/ import command for above sizes.

STSADM EXPORT in SharePoint 2007 is running on complete sites and not on a specific document library.
But you should be able to export multiple GB - I would just recommend to set the flag "cabsize" to 1024:

Depending on the metadata situation, it might be easier to mount each document library as a network share and then use RoboCopy to do the copying.
You should be able to keep the metadata if both libraries have the same columns.
The following is a script that I used for migrating just files from 2007 to 2010.

The script takes 3 arguements - a users name (for log naming convention)
a source UNC path to the sharepoint library
and a destination unc path to the sharepoint library

net use y: /delete
net use z: /delete

net use y: %2
net use z: %3

echo on
mkdir "z:\Documents\MIGRATED DOCUMENTS"
robocopy "y:\%2" "z:\Documents\MIGRATED DOCUMENTS" /Z /XD Forms /MIR /R:5 /FP /ETA /LOG:robocopy-%1.review_mat.log

net use y: /delete
net use z: /delete
