## Description

**As** a project admin  
**I want to** be able to change a project's identifier without invalidating old links  
**so that** I can change (e.g. shorten) them for usage in project-based semantic work package identifiers

**Acceptance criteria**

  - When a project identifier is changed, the old project identifier will still redirect to the project (as well as the new one)

  - A project identifier that was used once can only be reused in the same project in which it was used first

**Technical notes**

  - <https://excalidraw.com/#room=87a9e3fee5893ce524af,ztD0VCk8dOQOpx8GFWoVZA>

  - We need a new join table for project identifiers

  - We need a separate table to connect project based sequence numbers with actual work packages (columns `project_id`, `sequence_number`, `work_package_id`) and probably do it in this ticket to get it done earlier

**Out of Scope**

  - Allow to search by a project's identifier
    
      - global search
    
      - project selector
    
      - project filter (include projects)

**Permissions and visibility considerations**

  - Nothing changes here. Everyone who was allowed / disallowed to change project identifiers is still allowed / disallowed to change project identifiers
