\ Boot the new installation and use the -W option of the alt_disk_install

\ See the man pages for details
\
\ alt_disk_install Command
\ http://publib16.boulder.ibm.com/doc_link/en_US/a_doc_lib/cmds/aixcmds1/alt_disk_install.htm
\
\ image.data File and creation
\ http://publib16.boulder.ibm.com/doc_link/en_US/a_doc_lib/files/aixfiles/image.data.htm
\
\ mkszfile Command
\ http://publib16.boulder.ibm.com/doc_link/en_US/a_doc_lib/cmds/aixcmds3/mkszfile.htm
\
\
\ So for the doing. Read:
\ pSeries Administration and Support for AIX 5L Version 5.3
\ http://www.redbooks.ibm.com/redpieces/pdfs/sg247199.pdf
\ Chapter 3.6 to 3.8
\ because it shows all nessessary steps and should answer most of your
\ question
\
\ Addtional Information about converting from JFS to JFS2
\ Steps in case the alt_disk_install shell create jfs2 filesystem. Used
\ ONLY if the runing kernel is 64bit All steps are untested and can lead
\ to an unbootable system!
\
\ 1) Create a new /image.data - any existing will be overriden.
\ $ mkszfile -X
\
\ 2) Move the file to /image.data4jfs2
\ 3) Edit the /image.data4jfs2 abd change the type to JFS2 and check also
\ the log entries
\ 4) Do the alt_disk_install with the -i option ( -i /image.data4jfs2 )
