I got the old SharePoint environment as follows:
WSS 3.0 Server + Config DB (SQL Express 2k5) : Windows Server 2003 Std 32 bit
Content DB: SQL Server 2005 Database (Separate Server)
into the new environment
SharePoint Server 2013 Standard: Windows Server 2012 R2 Std 64 bit
Content & Config DB: SQL Server 2012 SP1
what steps do I need to know and what are my options to successfully migrate the sites with InfoPath workflow ?
