onmode -b
User asked whether to use 'onmode -b 11.70.xC4' to revert when upgrading from IDS 11.70 FC4 to 11.70 FC8. Responses clarified that onmode -b converts database format for version compatibility. Initial answer suggested it's unnecessary for minor upgrades, but was corrected—onmode -b may be needed even between minor versions. Advice was to execute onmode -b on the newer version to see available options before proceeding.

HI,
I want to upgrade ids from 11.70 FC4 to 11.70FC8.
I am writing the proposal.
Could I use the command 'onmode -b 11.70.xC4' to do the revert.
thanks for your time.
Hello.
In order to revert minor version upgrades, you might only stop the engine, and
restart on the oldest version.
Onmode -b is only needed for version number changes, when you migrate from
11.70 to 12.10, for example...

hi
When you convert a database server, several modifications make the format of
the databases incompatible with the older version. The onmode -b command
modifies data so that the earlier version of the database server can access
it. In some cases the format of the databases is compatible between versions
and the onmode -b command is not needed.
you can view onmode -b in 11.7 infocenter .
That's not necessarily true.
Even beteen minor version onmode -b may be necessary.
The only way to know is to execute onmode -b on the newer version and see
the possible options.

AFAIR a current example is 12.10.xC3 and 12.10.xC4
