Absolutely not.
SQL 6.5 is a totally different architecture to SQL 7 and onwards.
SQL 6.5 is nearer to SyBase on UNIX than it is to SQL 7 on Windows.
You can connect a SQL 7 database to a SQL 2000 server though.
Your options are
1. Data Transformation Services (DTS)
2. BCP
DTS will require a direct connection between your SQL 6.5 and SQL 7 box. I used to do this regularly to bounce data from a clients SQL 6.5 box into our SQL 7 datamart.
I've not used BCP for ages, but it used to be a blazingly fast input/output mechanism for data.
