Media Server v.7.0.4. will work in D7.0.3?

before upgrading dolphin to 7.0.4, i need to ask to my provider to update the Media Server.

So before jumping in and hit the wall (just in case)... if i ask for the MS update will my D 7.0.3 still work?

Dolphin 7.0.3 can work with new Media Server 7.0.4 but user's will no be able to create rooms in chat.

Dolphin 7.0.4 can work with old Media Server 7.0 but the same problem - user's will no be able to create rooms in chat.
