I am looking for a solution for interacting (read / write) with an old NAV 5.0 (SP1) Database. The installation uses the legacy format .fdb rather than SQL.
I couldn't find yet any ODBC drivers that would work and no other solution, so any suggestions would be welcome.
Do a technical upgrade to 2009 R2 and you can have web services.
That's is a good suggestion. As long as the customers license allows it.
