We are having one client who are having coexistence with 2000+ old mail boxes in 2007 and balance in 2010 i hope new one.
now they want us to migrate both versions directly to 2013 is there any way to do the same i got below 02 links but still i am not confident how to do the same.
as per my understanding we need to first migrate it to 2010 then 2013 please correct me if i am wrong...

Personally if this was a previous migration and stopped half way through I would upgrade all your services/mailboxes/public folders to 2010 and then introduce Exchange 2013. Having too many variables can get messy and you are likely to forget/miss steps a long the way.
If you have the opportunity to finish the first migration I would do so. But if they are pushing for 2013 it is supported. The benefits I see going straight to 2013 is that you don't have to migrate your mailboxes twice, because both 2007 and 2010 are supported to migrate directly to 2013.
Will.
