* After the user clicks to accept Begin of the deletion the project based identifiersEnd of the deletion we start a background job to generate the new identifiers (<mention class="mention" data-id="71645" data-type="work_package" data-text="#71645">#71645</mention>) and show a progress bar.

* While the job is running, it should not be possible to change the setting.

* When the user closes the page and navigates back to it while the job is running, the progress bar is shown and the setting can not be changed.

* When the background job is finished, the page reloads, the new setting is set to project-based identifiers and can be edited again

* It is Begin of the insertionNOTEnd of the insertion possible to abort the background job. Begin of the insertion~~WhenEnd of the insertion Begin of the deletion WhenEnd of the deletion it is aborted, the page reloads and the setting is set to global numeric identifiers and can be edited Begin of the insertionagain~~End of the insertion Begin of the deletion againEnd of the deletion


**Technical notes**

* When selecting global numeric identifiers (after project-based identifiers were active before), the already existing semantic identifiers are not deleted (so that we can still resolve URLs with semantic identifiers) Begin of the insertion

* We need an algorithm / class to generate short project identifiers. This should be written in a way so it can be reused and applied when a new project is created.End of the insertion


**Permissions and visibility considerations**

* This is visible to everyone who is allowed to access and change global settings


**Translation considerations**

* Begin of the insertionKey terms are

* Instance-wide numerical sequence

* Project-based alphanumerical identifiers
