It sounds like you are trying to migrate your 2.3 site and upgrade it - correct? So go through the migration part first (follow documentation on that). Once you have it moved and working, then start on the upgrade - I suggest maybe going to 2.7 first and then to 3.2. Backup everything first.
You say you have been trying but you haven't told us what EXACTLY you have done and where you have gotten stuck. We need specifics.
