Lync 2010 to 2013 migration - Moving the conferencing directory ?

Question

I am in the process of finishing our migration from Lync 2010 to 2013.
Reading the technet page, I don't see any mention to migrate the Lync 2010 Conferencing Directory to 2013.

But doing some quick research, I see that some blog are suggesting of doing it:

All my users have already been migrate to the Lync 2013 Pool.  No problem so far.
But I am still wondering if the Lync 2010 conferencing should be move or not?
thanks
John

In step 7,

The following user account information does not move to the new server.
Meeting content. In order to move the content shared during a meeting, for example PowerPoint, Whiteboard, attachments or poll data, use the
-MoveConferenceData parameter as part of the Move-CsUser cmdlet.
====
Did you move users with the GUI or with move-csuser -MoveConferenceData? 
If you moved with the GUI, the conference data noted above isn't moved.  If you think your users would care about this, you could move the directory to 2013 and forget about it.  Otherwise, you could just remove it as you decommission the 2010
pool.  It's rare that people would care about this data.
