Missing "Move to team project" menu option.

Hello,

we have Azure DevOps Server 2022 (19.205.33122.1) upgraded from TFS. 
I would like to move Work Items between projects, but there is no "Move to team project" item in menu. It is neither in Work Item nor in backlog list. I have sufficient rights (Project Administrator).
Project is created from Agile template.
Reporting is not enabled.
What could be the reason?
Which are the possibilities to move whole tree of Work Items. E.g. move Epic with all childs.
