Transport Wotlk and cataclysm RDF to MOP patch

Hello everyone

I heared that there will be a transport for WOTLK and Cata Dungeons to MOP frostworlf patch

My questions are:
1-is it true ?

2- when it will be transported ?

3- can anyone tell more explanation and details about the rdf of wotlk and cata update ?

thanks in advance.

Honestly I believe that it is not true , I remember Q&A streams back when Warmane was created they specifically explained that there is a huge difference in the script and that they basically have to rewrite most of the stuff from the scratch.
