The system you get out of the box has no synchronisation built in.
You can either design so that you don't need it
OR
Build your own interop system (say using posted values or cookies).
Your own system could have two copies of session values or use a
database. Database could knock performance depending on your situation.
First prize is probably to design so you don't need it.

I'm moving gradational from ASP.old to ASP.NET. In the meantime, I must
use both Sessions - of ASP.old & ASP.NET. How can I synchronize between
them ?
