What you need to be careful of is to make sure there are no database changes when running the upgrade script, since you would be bypassing that step..
The scripts are called altertable that are executed from the upgrade script.
So if there are changes then a database import from your older version would not have those changes.

I think in this case you should be fine with the database import.
I do not believe any part of the database was modified between the two UBB versions.

If not you will need to setup the new server with say php 5.4 or 5.6
Move the files and database from the old server.
Set the proper permissions for files and folders
edit the includes/config.inc.php file for any path or user/password changes and database name etc
Browse to the board to make sure it is in proper working order
Then follow the upgrade procedure document
over write the files with the new version, excluding the specific files as noted
Then run upgrade.php not install.php

Then you can upgrade php to 7x
