Recovery of MaxDB 7.5 content server 6.40 to MaxDB 7.9 content server 6.50

Hi,

I am trying to upgrade from SAP Content Server 6.40 with MaxDB 7.5 on 32-bit platform, to SAP Content Server 6.50 with MaxDB 7.9 on 64bit architecture.

I have DBStudio 7.9.08.25 and 7.9.08.8 MaxDB instance for the SDB and CDB on the target server

I have also created backups of the SDB and CDB on the source server and copied the files to the target server. However, when I try to receover the medium, I get error message "-24994 Runtime environment error 1, wrong file or device name".

I have reviewed sap notes 129352 and 767598. I am trying to find the glossary entry "System Copy" as mentioned on the first page of 129352, but to no avail.

Any help as always greatly appreciated.
