Hi,
I have never seen conversion of NBE 5.1 conversion to NBD 4.5
I am afraid that this is not possible. (Looking forward to see a way to do this in this thread, if it is possible :) )
cat_convert.exe -s
-v] source_file_directory
There are two switches a2b and b2a
-a2b Convert NetBackup 3.4, 4.0V, 4.5 ASCII format catalog .f file(s) to NetBackup
4.5 binary format .f file(s). Do not use -a2b with -b2a.
-b2a Convert the NetBackup 4.5 binary format catalog .f file(s) to NetBackup 4.5
ASCII format .f file(s). Do not use -b2a with -a2b.
NO where it is specifies that NB 5.1 catalog can be converted to 4.5.
