Q: Does alt_disk_copy convert JFS filesystems to JFS2? A: Yes! Starting at 6100-04 , a new flag was introduced that would convert JFS filesystems to JFS2. We now have the -T which does the conversion. http://www-01.ibm.com/support/docview.wss?uid=isg3T1011055   Here’s an example of converting rootvg file systems from JFS to JFS2 using alt_disk_copy .   My lab system was migrated from AIX 5.3 to 7.1 via nimadm .

Convert rootvg JFS file systems to JFS2 with alt_disk_copy

Starting with AIX 6.1 (TL4?), you can use the alt_disk_copy command to convert rootvg file systems from jfs to jfs2. The man page for the alt_disk_copy command states the following:   -T Indicates that you want to convert JFS file systems to JFS2 file systems during the process of recreating the rootvg volume group on target disks.   As an example, to clone a running systems rootvg to hdisk2, and convert the rootvg file systems from JFS to JFS2, you would run the following command:   # alt_disk_copy -T -d hdisk2   Good to know!
