The Access to SQL Server upsizing wizard is the best way to start. There's a different version for each version of Access.
The Upsizer that comes with Access '97 does a pretty good job but won't convert parameterized queries. This leaves you in the position of having to code them yourself. I've written code to convert these but moving up to the Access 2000 upsizing wizard is another solution.
The Upsizer that comes with Access 2000 converts parameterized queries into stored procedures. For this reason it may be worth converting your Access '97 db to 2000 first and then using this Upsizer.
I've also written an article on converting Access database to SQL Server. It's from 1999, before Access 2000 was available but much of it is still relevant. It's available for free at http://www.NovickSofware.com/Articles.htm
One other thing: I've found that it's a good idea to convert in multiple steps. First, Upsize the database schema, then move the data. The upsizer sometimes chokes on some of the data movement. I generally use DTS to move the data, not the upsizer, but sometimes you can even use Access copy and paste to do the job.
