Question:
In connection with a release update, I want to copy all files from a
file set which is now placed in an InterForm400 version placed in lib AFP3812OLD?

Answer:
You can copy manually using the object commands.

Example:

We will copy all overlays from SAMPLE in lib APF3812OLD into fileset TEST in
a new version of InterForm400, which is placed in lib APF3812.

1.First create an empty fileset TEST in the new version (the version you want
to copy to)

2.Enter CL command:

CPYF FROMFILE(APF3812OLD/APFFMTP) TOFILE(APF3812/APFFMTP) FROMMBR(SAMPLE)
TOMBR(TEST) MBROPT(*REPLACE)

3.Enter CL command:

CPYF FROMFILE/APF3812OLD/APFMSTP) TOFILE(APF3812/APFMSTP) FROMMBR(SAMPLE)
TOMBR(TEST) MBROPT(*REPLACE)

4.Enter CL command:

CPYF FROMFILE(APF3812OLD/APFPAGP) TOFILE(APF3812/APFPAGP) FROMMBR(SAMPLE)
TOMBR(TEST) MBROPT(*REPLACE)
