ASP (VBScript) to PHP Converters?

Howdy! I have started searching around for VBScript to PHP converters and was hoping that the group might have some recommendations. My new position places me squarely into the middle of a Windows shop and one of the reasons that they wanted me here was to help them take the steps to the next levels. The first steps that I want to take with them are moving away from ASP, .NET and IIS to PHP, C++ and Apache. We have a pretty robust MS-SQL Server replication system, but I will introduce them to MySQL & PostGres for certain projects. I know that ASP to PHP converters aren't perfect, and a lot of the existing code was generated with Dreamweaver which has introduced some bloat. I feel that if we can get part way there that the rest can be cleaned up reasonably easily. I look forward to hearing suggestions. TVMIA!
