Transport KM rooms as entry point for broadcasting from Portal 7.01 to Portal 7.4 possible?

Hallo together,

is it possible to transport entry points (for broadcasting) from one portal to another?

For our upgrade BW 7.01 to BW 7.4 we want to transport the KM Content (including the rooms).

Transporting the rooms and room structures is no problem, but the transported rooms are not visible in ENTRY POINTS -> My Room Folders.

Only rooms that are newly created in the 7.4 Portal are visible in that folder.

Is there are way to make the transported rooms also visible there?

Thanks and best regards!

Christian
