To my knowledge, there is no way to convert a JFS to Enhanced JFS. You
have to delete the file system and then create it as type JFS2.

You also have the option to use a JFS as long as it is "Large File
Enabled". This was an interim feature developed for JFS so it could
handle files larger than 2GB. Again, I know of no easy conversion to
make JFS large file enabled.

Since you are copying a new file from another system, you should have
the option to put it wherever you like, so just create a new JFS2 or
LFE-JFS and use gunzip or cpio in that file system.

Other solution may be to use pipe:

gunzip -c 10gr2_aix5l64_database.cpio.gz | cpio -icuvdm

and extract files from cpio archive without first creating a file over 2 gigs
size.
