Most stable current V11 release

Same here. We were so fed up with 11.2 with various EngHFs that we jumped to 11.3 when it came out about last Christmas, bypassing 11.2.1 altogether, which didn't seem to be much different anyway. Now we are on various EngHFs on 11.3. :-( Was tempted to jump to v11.4, but didn't do it for a missing bug fix that we needed. Also noticed that HF1 came out a day after 11.4 became available. We had F5 people do the upgrade from 10.2.x to 11.2 for us last year, and such a relief to see them having the angst rather than I myself. :-) So I can only give you my observations of the upgrade. First of all, the upgade process did not parse the 10.2.x conf to convert it to v11 conf sucessfully. It could not load the conf at all. Secondly, it seemed that one could not revert to a previous v10.2.x partition once a v11.2 was installed: it went into a boot loop in our case. There was a clean re-installation in the end. "/usr/libexec/bigpipe daol" was used to convert the v10.2.x conf to v11.2 after the upgrade. v11 is very different from v10.2.x, and has subdirectories for different partitions. There was a bug that was later fixed in a HF to load the confs in these directories correctly, in the right order. I'd say v11.3, and perhaps v.11.4 for that matter, might be able to handle the upgrade better, as they have incorporated all those hotfixes from v11.2.x. I still have a few v10.2.4 devices to upgrade, and what worries me is that the current root partition might not be just big enough for upgrade to v11.4.x. The root partition of v11.2 seems to default to 287M. A list of the default size of the root partition of various releases would help planning upgrades. If you have upgraded from a v10.2.x to v11.3 or v11.4 successfully, it might be wise to take a backup, do a clean re-installation and reload the conf from the backup. You will have a larger root partition, which will set you up well for a future major upgrade. -Jie
