Hi again wmp,<br />
<br />
If I upgrade AIX6.1 to a new TL or SP or both using smitty update_all with this two options:<br />
&nbsp; COMMIT software updates? no<br />
&nbsp;SAVE replaced files? yes<br />
<br />
OR<br />
<br />
If I upgrade an AIX6.1 to AIX7.1 with the same options on the smitty update_all.<br />
<br />
If there's a problem, how can I rollback the previous OS?<br />
<br />
Thanks

rollback on AIX

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
