SilentConfigurationUpgradeService.php (looked in 8.7) says the value is removed as SYS/setDBinit but moved to DB/Connections/Default/initCommands.
So to me it looks like it shouldn't finally be removed but instead by moved/renamed? Currently the silent-upgrader seems to handle that behind the scenes?

Stefan i tested an upgrade from 7.6.x to 8.7.20. Yes the silent-upgrade move the values from SYS/setDBinit to DB/Connections/Default/initCommands when u do the upgrade wizzard.

After you have done the upgrade wizzard. The option for edit SYS/setDBinit is still in the install tool > all configuration. Becouse its in DefaultConfiguration.
Same happens when you have a clean new 8.7 installation.

So my suggestion is to remove this from DefaultConfiguration (DefaultConfigurationDescription), so its no longer available inside install tool > all configuration.

I tested an upgrade from 7.6.x to 8.7.20 with the patch applied. The silent-upgrade still works and move the value to new location.

DB/* settings¶

Currently in 8.7 there are no options to change DB/* settings at all. Atleast i do not find them :) We can create new feature request to make all DB/* settings editibale in install tool (atleast for connection DEFAULT)?

There are two more options in the DefaultConfiguration wich are are moved to new location:

• SYS/dbClientCompress
• SYS/no_pconnect

changing this value in install tool do not trigger silent upgrade process. They are written in LocalConfiguration and have no effect.
