More modern and user friendly interface
Easier editing, fewer formatting issues
Better page organisation and navigation
Clearer permissions and version history
Easier for new people to learn
Migration effort, even if the content is limited
Formatting will not transfer automatically, some pages need rebuilding
Need to manage two systems during the transition
Slight learning curve for those used to TWiki
No added benefit from Atlassian integration since other tools are not used
How many pages need to be moved, and how much time will it take?
Does the current TWiki cause problems that Confluence would solve?
Will contributors find Confluence easier and maintain pages more regularly?
Is Confluence widely accessible at CERN for everyone who needs it?
Is there a long-term plan at CERN to favour one platform?
Are we willing to maintain documentation more actively if moved?
