[OpenIndiana-discuss] failed upgrade from OpenSolaris to OpenIndiana

[baldyeti]

Hello, I've tried following the instructions from the wiki:
<http://wiki.openindiana.org/oi/Upgrading+from+OpenSolaris>
The thing is I have a smallish (6GB) root FS, and ran out of
space midway through the first step (upgrading from OS2009.06
to snv_134).

Could someone help me
*) reclaim the disk space that got eaten by downloaded packages
(hos to purge these?)
*) perhaps perform the upgrade piecemeal (e.g by subsystem or
package groups instead of all at once)

Is OI supposed to run wherever OS did? Then my HW should be
supported and it might be simpler to install the latest OI ISO?

Tx in advance!
