Hi ADSM'ers

I am migrating from a server ADSM V1-2 (OS2) to a server ADSM V2-1 (AIX)
by the function EXPORT.

Export server filedata=none and
Export node nodex filedata=backup vol=volx

It is long, very long, too long: 24 hours per tape 8mm and I have 20
tapes to export and import.

While I import the data, the server is completly dedicated to this
process. If I do an administrative command, the import freezes an I
have to start the import again.

The function import seems slow and unsuitable.
What do I wrong ?
How can I do ?

Thanks
