How to download spool requests and then import t again at a later stage

Hi All,

When are in the process of doing a Combined Upgrade and Unicode conversion. So we need to download the spool requests and import those once after the upgrade is done..

I have already tried doing it using SP01 Spool request ->Forward ->Export as text, but not all requests are getting downloaded, only 200 out of 20,000 are getting downloaded..

Can anybody help me with other alternative?

Regards

Thilip Kumar
