question about in-place upgrade
John Smith doubted an in-place upgrade from 11.70 to 14.10 was possible on AIX because the versions support different AIX levels. Paul Watson and Art Kagel said it works: shut down 11.70, upgrade AIX to 7.2, then start 14.10; rollback uses onmode -b then an OS downgrade. Vladimir Kolobrodov said 11.70 runs fine on AIX 7.2 though uncertified, and 14.10 is unsupported on AIX 7.1. John agreed.

Hello i'm suprised !!!! on this link it's said that we can upgrade in-place from 11.70 to 14.10 BUT 11.70 is compatible with AIX 6.1 and 7.1 and not with AIX 7.2 14.10 is compatible with AIX7.2 but not with AIX 6.1 and 7.1 so can we really do an in-place upgrade from 11.70 to 14.10 ?? https://informix.hcldoc.com/14.10/help/index.jsp?topic=%2Fcom.ibm.admin.doc%2Fids_admin_1399.htm Upgrading (In-place migration)Upgrading is a special case of migration that uses your existing hardware and operating system. You install a new or improved version of the product in a different location from your current version on the same machine. You can copy your configuration file and add new parameters. When you start the new Informix instance, the database data is automatically converted. For example, you can upgrade from Version 11.70 to Version 14.10. ------------------------------ John Smith ------------------------------ #Informix
You can do an inplace from 11.7 to 14.10 but looks like you getting caught by the OS. Have you tried to install 14.10.FC < 5 on AIX 7.1 ? Cheers Paul
John:
You can do the upgrade in-place from 11.70 to 14.10, but on AIX you have to jump through a few hoops:
Shutdown 11.70 under AIX 7.1/6.1
Upgrade the OS to 7.2
Start up 14.10 to perform the server upgrade
You just cannot perform the upgrade of the engine safely under the earlier AIX versions or run the earlier engine safely under the newer OS version. And rolling back means reversing that:
Downgrade the Informix disk structures with onmode -b <version>
Downgrade the OS
Start up 11.70

Informix and AIX. While 11.70 is not officially certified on AIX 7.2, it'll practically run fine there, especially later fixpacks (xC9W2). The lab runs some comparative benchmarks with 11.70 on AIX 7.2 and POWER9. 11.70.FC1 and few earlier fixpacks may not install from media, but if the INFORMIXDIR has been transferred (rsync,tar) it'll work just fine. The 14.10 is NOT supported on AIX 7.1 starting from xC1. Hope this helps. If anyone encounters issues with 11.70 on AIX 7.2 - please share details. ------------------------------ Vladimir Kolobrodov ------------------------------
Have you tried to install 14.10.FC < 5 on AIX 7.1 ? ==> No, i don"t make any step without preparing, and it"s opposite of IBM compatibility matrix ------------------------------ John Smith ------------------------------
If there is OS upgrade Yes i agree:) ------------------------------ John Smith ------------------------------
