What EVENT will be triggered when updating the i3 server?

Hi, there is no such event, but we can try to add IR.EVENT_EXIT in Server

In which case you need it? Why can change the project on the server?

To store values/variables at the exact time before the server gets an update. Or to do special switchover procedures for a backup server, etc. in case the new serverfile isn't working as expected.

I understand this) I do not understand when you can change the server project on the object? Is this a common situation that can occur without your permission?

it's not usual when an installation is finished, but for development. i have a server project here where i use variables to store different values/modes/etc. normal use. but i don't want to store them always in the database when they are changed. but i want to save the values in the user-database in the case the server gets a project update, especially while developing, so i can reload the variables/values right after the new projects starts up to work.

I understand, but I think you can use database always and have no problems. We will don't develop additional EVENT
